What is an Amazon storefront?
A seller's public page listing everything they offer - and a sourcing goldmine.
Every Amazon seller has a public storefront page listing their current offers. Buyers rarely look at it; sourcing sellers do, because a competitor's storefront is a curated list of products someone with your business model already sells profitably.
Storefront sourcing means feeding a successful arbitrage seller's storefront into a reverse search and finding retail sources for the same products. It is legal and universal - your storefront is public too - and it compresses product research from guessing to copying what demonstrably works, then competing on execution.
