Find winning products.
Source them. Sell them.
SourceLynx validates real Amazon demand, algorithmically matches suppliers, and publishes directly to your Shopify store.
Stop selling the exact same products that typical platforms flood the market with. Find highly profitable items that millions of other sellers haven’t even discovered yet.
Find AliExpress, eBay, Etsy, Temu, and SHEIN items to resell on your Shopify store.
How it works
How etaLynx works
Three steps powered by real demand data — not hunches.
Discover real demand
Search Amazon by brand, keyword, or BSR range using live Keepa data. Every result is a product people are actually buying — not a guess.
Find live eBay sources
For every Amazon product, etaLynx searches eBay in real time for matching listings — comparing price, shipping, condition, and seller rating to surface the best source.
Fulfill with confidence
A Chrome extension connects your Amazon order to the right eBay listing automatically, tracks your margin, and flags a replacement the moment a source runs out.
Every eBay match is verified live at search time — never a stale cache. Pricing shown always reflects what you’d actually pay right now, with a freshness note on every listing.
Building a Shopify-focused sourcing tool too — ShopLynx is coming soon.
