Founder, Aftermarket Arbitrage · 18 August 2026
Reverse sourcing is one of the best sourcing methods in online arbitrage, and it is where a lot of our strongest finds start. Instead of hunting shops and hoping, you start from products that are already proven to sell, then hunt backwards for the retail offer.
The method, step by step
- Start on a storefront, not a listing. We begin with a specific type of FBA seller and open their storefront. Every listing on it is a product that seller has already proved sells. The exact seller profile is the part that makes this work, and I keep it for members.
- Pick the listings that actually sell. Real monthly sales come first, whatever the margin looks like. A listing doing 300 sales a month is worth digging on, and one doing five is not. Keep the dead ones too, they come alive when they hit clearance or a price drop.
- Check the sellers and the buy box. Monthly sales get shared, so fifteen sellers means your slice is a fraction of the headline number. If Amazon is on the listing and holding the buy box, walk away.
- Run it through SellerAmp, then Google Shopping. SellerAmp gives you the analysis on the listing: sales rate, fees and profit at any buy price. Then use its Google Shopping feature, which matches the title to a Google search and surfaces discounted online offers of that product in seconds.
- Check the pack size, then the profit. A £10 single at retail against a £28 twin pack on Amazon is no deal at all. Confirm it is the same product and size before any money moves.
Before you buy
- Barcode match confirmed, never a title match.
- Same pack size on both sides, count the units.
- 20% ROI after fees, even when the sale feels certain.
- Amazon is not sat on the buy box.
- Judge the data, not the product.
Most listings you reverse lead to a retailer whose everyday price leaves you nothing after fees. That’s not the method failing, it’s what shelves look like: my own software hunts this lane around the clock and rejects nearly everything it checks. Some weeks the watch list produces nothing at all, and nothing on this page is a promise of income.
That is the principle, and the principle alone finds deals. It is not the full method though. There are a few extra steps that decide whether you find one deal or a repeatable pipeline, and I teach those inside the membership. Book a free call or join us for the full methodology. Then watch where the engine is finding this week on the live websites board.
