Built for Amazon
Everything You Need to Shop Amazon Smarter
We went deep on Amazon before going wide. Dupely works the second you land on a product page. It finds the identical dupe and scores it. It surfaces daily price drops and deals of the day. It flags the bestsellers and viral products that have cheaper twins. And it hands you promo codes before checkout, even the ones that haven't dropped yet.
Built for Amazon first. More marketplaces on the way.
