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, then 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. 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 5 September 2026. 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. Amazon describes it as a free mobile application for managing your business, and it will scan a barcode or read a product with the camera to show you whether the item is already listed. It is 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 middle of the list. It is not built to model your prep cost, your VAT position or your ROI floor, it does not plan your trip, and it does not watch retailer prices for you. It is job three at a basic level and nothing else. 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 own site, checked on 5 September 2026, also lists eligibility checks, described as "Know if you can sell a product before you buy it. Restrictions and gating flagged." That is their claim as written on the day, so job four is on the list too. It is worth checking on the trial how the 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 at any time, 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 on the day we checked, so we are not quoting one.

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, and it leans online

BuyBotPro calls itself an 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 listed UK monthly pricing on the day we checked at £24.95 for Basic, £34.95 for Pro and £99.95 for Enterprise, with a 30-day free trial and no contract. 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: most of your sourcing happens at a desk on retailer websites and you want a verdict rather than a dashboard.

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 pricing page would not load for us on the day we checked, 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 15 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.

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 guide to what any deal analyser has to get right covers the checks worth testing on a free trial.

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 the day we checked. 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.
• 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.

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.
