The best retail arbitrage apps for UK sellers in 2026

Search for the best retail arbitrage app and you get a list of profit calculators. That is a useful list, but it answers a smaller question than the one most UK sellers are actually asking. A calculator tells you whether the thing in your hand is worth buying. It does not tell you which shops to walk into, what order to drive them in, or what to do on the four evenings a week you cannot get out of the house.

This guide is a category piece rather than a head to head. It sets out the jobs a retail arbitrage app has to cover, goes through the tools UK sellers actually use and says plainly which job each one is for, including the cases where our own product is the wrong answer, and then covers the two things most app reviews skip: what an app has to get right standing in a real shop, and whether it follows you back to the desk. Written for someone three to twenty-four months in, doing store runs at weekends and sourcing online in the evenings.

What a retail arbitrage app actually has to do

Retail arbitrage is a loop, not a single decision, and the loop has seven distinct jobs in it. Almost no tool does all seven, and the reason people end up paying for three subscriptions is that they bought three tools that each cover a different slice.

• Find shops worth the diesel - Which chains near you carry clearance that resells, and which branches are the large formats rather than convenience stores with no general merchandise.
• Order the trip - Five stops in a sensible order is a morning. The same five improvised is a day, and the last two get skipped.
• Call the deal in the aisle - Referral fee, fulfilment fee, your prep cost, your VAT position, and a profit and ROI figure you actually trust, in the time it takes to pick the box up.
• Tell you whether you can sell it at all - A 60 percent ROI on a brand you are gated out of is not a deal. This check belongs before the trolley, not after the invoice.
• Show the history, not just today - Price, Buy Box and sales rank over time. Today's price is a snapshot and snapshots lie, particularly on lines that spike once a year.
• Keep working between trips - Retailer and brand price drops caught while you are at work, so the weeks you cannot drive anywhere are not dead weeks.
• Remember what you bought - Cost, quantity, what it actually sold for, and which lines are worth restocking. This is the job everyone does in a spreadsheet until the spreadsheet stops being honest.

Score any tool against that list before you pay for it. Most of the frustration people express about arbitrage software is not that a tool is bad, it is that they bought something excellent at job three and expected it to do jobs one, two and six.

Single-purpose tools are not a weakness

It is worth saying this before the list, because category guides written by a vendor usually imply the opposite. A tool that does one job extremely well is often the right purchase. If your sourcing is already sorted, because you have five shops you rotate and you know them well, then the only gap you have is the aisle decision, and the best thing you can buy is the best aisle-decision tool. Paying for an all-in-one to use one fifth of it is not clever.

The all-in-one argument only holds when you genuinely have several of the seven gaps open at once, which is the common case for sellers in their first two years but not for everyone.

The tools, and what they cost

Every price and feature below was read on that company's own website on 14 September 2026, when this guide was last updated. Software pricing moves, so check the current page before you buy anything, and treat any figure in a blog post older than a month or two as a rough guide only.

The Amazon Seller app: free, and the floor everyone should start on

Amazon's own Seller app is free with a selling account, and Amazon's page for it says so plainly. That page lists barcode scanning among its features: scan a barcode or point your phone's camera at a product to see whether it is already in the Amazon store, then list it. It also mentions an FBA revenue calculator for estimating profit. That makes it a perfectly reasonable place to take your first ten scans while you work out whether you enjoy standing in a clearance aisle at all.

Where it runs out is the rest of the list. Amazon describes it as an app for managing your selling business from anywhere, not a sourcing tool, and nothing on its page covers choosing which shops to visit, ordering a trip, or watching retailer prices between trips. It covers job three at a basic level, for free. Nobody should be paying for software before they have outgrown the free one.

SellerAmp SAS: the analyser most UK sellers land on

SellerAmp is the established deal analyser in this niche and it deserves the reputation. Job three is where it has spent years and it shows: the single-product analysis is deep and the settings are mature. Its pricing page says every plan includes eligibility and IP alerts, alongside the profit calculator with fees, ROI and profit, historical price and sales charts, and Buy Box analysis, so job four is on its list too. It is worth checking on the trial how that answer surfaces while you are stood in the aisle, because that is where a gating verdict earns its keep.

Pricing on selleramp.com is shown in US dollars: Getting Started at $19.95 a month, Getting Serious at $29.95 a month and Going Pro at $49.95 a month. The page states that all plans start with a 14-day free trial and can be cancelled anytime, and notes that UK pricing is available and that annual billing gives two months free. We could not see a GBP figure on the page itself, so we are not quoting one. The same page lists a Chrome extension, a web app and a mobile app on every plan.

Buy it if: you want the deepest single-product analysis and you already know which shops you are driving to. That is a real and common situation, and in it SellerAmp is the simpler buy than anything all-in-one, ours included.

BuyBotPro: automation-led, with an app for the shop

BuyBotPro describes itself as a fully automated online and retail arbitrage deal analysis tool, and the emphasis on automation is the honest description of the difference: it is built to make the decision for you rather than lay the numbers out and let you make it. Some sellers strongly prefer that. Others want to see the working.

Its own site lists UK monthly pricing at £24.95 for Basic, £34.95 for Pro and £99.95 for Enterprise, each shown plus VAT, with a 30-day free trial and no contract. The same page lists a desktop Chrome extension and says its BuyBotGo retail arbitrage mobile app, for Android and iPhone, is included free. That 30-day trial is genuinely generous, and long enough to test a tool across a full month of sourcing rather than a weekend.

Buy it if: you want a verdict rather than a dashboard, and most of your sourcing happens at a desk with the occasional shop visit.

Keepa: the data layer, not an app for the aisle

Keepa is not really a competitor to any of the above, it is the price and rank history that most of them display. If you are buying seasonal lines, or anything where the Amazon price today is not representative, the history is the thing that stops you paying spike prices for a line that sells for half that eleven months of the year. Its subscription page returned an error when we tried to load it on 14 September 2026, so we are not putting a number on it here.

Worth knowing: several tools, retailscout included, embed the charts, so check what your main tool already gives you before adding a separate subscription for the same data.

retailscout: built around the trip, with the analysis inside it

We build retailscout, so read this row with that in mind and check the claims. Our starting point was jobs one and two, because they were the ones nobody in the UK was covering. When we mapped the sourcing landscape we ended up with 17 UK retailer chains and over 13,000 individual store locations, filterable by chain and by store format, which is what turns a vague idea of a Saturday into an ordered route you can actually drive.

The analysis half sits inside the same membership. Scan a barcode, search an ASIN or type a product name and the deal analyser pulls sales, Buy Box, every Amazon fee and a profit and ROI figure worked out on your own cost, prep and VAT settings, alongside price and rank history and a 0 to 100 buy score. Between trips, the price drop feeds are refreshed through the day, Brand Radar runs daily sweeps and Retailer Radar runs twice a day, so job six is covered without a separate leads subscription. Job seven is the end-to-end encrypted buysheet, which we cannot read even if we wanted to.

Job four runs inside the same scan. Connect your Amazon selling account, and the app checks whether you can list a product: every item you analyse comes back with a "Can I sell this?" answer against your own account, and if the answer is approval needed, the approval link is right there. Before you drive anywhere, the "What can I sell?" scan runs a representative brand list through the same check and sorts brands into sell now, approval needed and restricted, so you know which lines are yours before the trip rather than after the invoice. The connection is read-only and you can disconnect at any time in Settings. Every paid membership includes it. We wrote up how to check whether you can sell a product before you buy it separately, including why a list of ungated brands from a Facebook group tells you nothing about your own account.

It is £14.99 a month for all of it, with a 7-day free trial and you can cancel anytime. If you want the analyser compared feature by feature rather than in a category list, our retailscout versus SellerAmp comparison does exactly that, and our SellerAmp, BuyBotPro and ProfitGo alternative guide takes each analyser in turn and says what you would be giving up by switching.

What an app has to get right in the shop

Feature lists are written at a desk, but a retail arbitrage app gets judged somewhere else: in a clearance aisle, trolley in one hand, phone in the other, with one bar of signal behind a wall of steel shelving. Most reviews never leave the desk, so here are five things to test on any trial, ours included, before you trust it with a Saturday. Do it in a real shop, ideally a big one on its clearance cycle, like the stores in our Tesco clearance guide for resellers, not at the kitchen table with a tin from the cupboard.

• Does scanning carry on with no signal? - Large stores are often poor for reception, and the back of the shop is usually the worst of it. An app that shows a spinner and then an error is an app you stop opening by the third aisle. Walk to the back wall on the trial and scan there.
• Does the first number need typing? - Profit and ROI both need a cost entered first, and typing is the slowest thing you can do with a trolley. A figure that needs no input, such as the most you can pay for this item and still make your margin, can be held against the shelf label with your eyes.
• What happens when a barcode has no match? - Plenty of clearance lines do not turn up on Amazon under the barcode on the pack. A good app treats that as an answer and gives you another way to identify the product, rather than a red error screen that makes you think the app is broken.
• Are the numbers yours? - A profit figure worked on somebody else's prep cost and VAT position is a guess with decimals. Check the app uses your own settings before you believe a single verdict.
• Can you sell it on your account? - Covered above, and it matters more in a shop than at a desk, because in a shop the next step is the till.

How retailscout's store mode is built for that

Those five questions are the brief store mode was built against, so here is how it answers them, described as it is designed. Every scan is written to a queue on your phone first and looked up second. Lose signal behind the shelving and you keep scanning; the queue clears itself when signal comes back, and there is no offline mode to remember to switch on before you leave the car, because you never know you are about to lose signal until you have.

The first figure on each result is max cost: the most you can pay and still clear the minimum ROI you set, so it needs nothing typed. Monthly sales come next, then any warning worth stopping for. A barcode with no Amazon match gets its own card with an option to read the front of the pack instead, rather than a failure screen. Tap any result and the full deal analyser opens, with the fees, Buy Box, charts, buy score and the eligibility answer for your own account. The quick screen answers fast, the full one answers completely, and you decide which one a product deserves.

Phone, desk or both

The other thing app reviews tend to skip is that most UK sellers in their first couple of years do not source in one place. The store run is at the weekend; the evenings are a laptop and a list of retailer websites. So the question is not only which app, it is whether the same tool follows you from the aisle to the desk and judges a product the same way in both.

Among the tools above, per their own sites on 14 September 2026, SellerAmp lists a Chrome extension, a web app and a mobile app on every plan, and BuyBotPro lists a desktop Chrome extension alongside its free BuyBotGo mobile app. The Amazon Seller app is a phone app. Keepa is the history most people meet inside one of the others.

retailscout is one membership across all three places. On the phone it is the store search, the route and the scanner. On a laptop the same account opens the deal analyser, the price drop feeds and the tracker on a bigger screen. And the Chrome extension opens the same analysis in a side panel beside any Amazon product page you have open, with a button to park the product for later. It is the same deal analyser underneath all three, so a product you park on a Tuesday evening and one you scan on a Saturday morning are judged the same way.

Where retailscout is not the pick

Three situations, and they are not hypothetical. We would rather you knew before you paid than after.

• You only want a profit calculator. If your store list is settled and the only gap is the aisle decision, SellerAmp is the simpler buy. You would be paying us for a route planner you will not open.
• You want the longest trial before committing. Ours is 7 days. SellerAmp offers 14 and BuyBotPro offers 30, both per their own sites on 14 September 2026. If a month of testing matters to you, that is a fair reason to start elsewhere.
• You are not in the UK. The store mapping, the retailer feeds and the fee maths are built for UK sellers on Amazon UK. Outside that, most of what makes us useful does not apply.

What we would push back on is the idea that stacking three subscriptions is inherently the professional choice. It is sometimes the right one. It is often just what happened.

How to choose in five minutes

Take the seven jobs and mark each one as covered, half covered or open. Then buy against the open ones rather than against the review with the best headline.

• Only job three is open, and you already know your shops: buy the best analyser and stop there.
• Jobs one, two and three are open: an all-in-one built around the trip will save you the most.
• Job four keeps catching you out: pick the tool that answers it before the trip, against your own account, not the one that flags it after you have picked the box up.
• Job six is your real gap because you cannot get out much: look at what catches retailer price drops, not at scanners.
• Job seven is the pain and everything else works: you need tracking, not another scanner.
• The shops you use have poor signal: put scanning with no signal at the top of your trial list, and test it at the back of a big store rather than at home.
• Nothing is open and you are just curious: stay on the free Amazon Seller app for another month. Tools do not create finds.

And whichever way you go, run the same real product through the trial of anything you are considering. Not a demo product, one you actually rejected last weekend. The tool that explains its number in a way you can argue with is the one worth paying for. If fees are where your numbers usually go wrong, our breakdown of Amazon FBA fees for UK sellers is a good thing to have open while you test.

The short version

There is no single best retail arbitrage app, there is a best app for the job you have open. The Amazon Seller app is the free floor. SellerAmp and BuyBotPro are strong at calling the deal, and if that is your only gap, one of them is the simpler purchase. Keepa is the history underneath most of them. retailscout is the one built around the trip itself, with the analysis, the drops and the tracking folded into the same membership, and a scanner designed for the back of a shop with no signal.

retailscout plans profitable sourcing trips and catches retailer price drops between them. It is £14.99 a month for the lot, with a 7-day free trial and you can cancel anytime.
