A dashboard of opportunities
Every product that cleared the profit gate, with the buy price, the sell price and the margin left after fees.
Step 1 of 3 · Source Product
Find the eBay listings you can buy cheaper on Amazon Prime
Point it at an eBay store. It reads the store's listings, finds the same product on Amazon Prime, and scores what is left after eBay's business fees. Anything clearing £0.50 is flagged as a target — with the evidence kept, so you can check any verdict later.

How a scan works
Four stages, run in order. Each one narrows what reaches the next, so the expensive checks only ever see candidates worth checking.
-
A
Select the store
Stores are kept or skipped on how many live listings they hold — an adjustable band, 1–1000 by default. Too small is not worth a scan; too large is usually a reseller, not a source.
-
B
Select the product
Products are kept on units sold, 2–1000 by default, so there is demand but not saturation. For each one it then finds the cheapest identical listing across competing stores — the price you would have to beat.
-
C
Match it on Amazon
Prime offers only, matched by title, then image, then specification. Pack size is a hard gate, never a tie-breaker: a 10-pack is not a 4-pack, and a match that gets that wrong turns a profit into a loss.
-
D
Score the profit
Cheapest eBay price to sell against cheapest Prime price to buy, put through the eBay UK business fee model. Clear £0.50 and it is recorded as a target; miss and the reason is recorded too.
What you get once you are in
Scans and campaigns
A scan checks one store. A campaign walks an entire store's catalogue, listing by listing, and can be paused or cancelled while it runs.
The evidence behind every verdict
Both listings side by side, the images compared, the fee breakdown, and why a match was accepted or rejected. Nothing is a bare number you have to trust.
Price and stock changes
Products are re-checked over time, so a margin that quietly disappeared shows up as a change rather than a bad order.
Getting an account
Access is granted, not self-served — the scans cost real API calls, so an administrator approves each account by hand.
An approved account reads the catalogue. Starting your own scans and campaigns is a further grant an administrator makes for 30 days at a time and renews on request — when a grant runs out the account keeps everything it could read and stops being able to start new work. Running scans also needs your own Anthropic API key and the browser extension installed once, so the work bills to you.
