Here return is a noun, meaning an item that has been returned to its place of purchase. Stores sometimes have a sign up saying, "no refunds, no returns". So, they're warning their customers", Once you buy something, that's it. You can't bring it back and you can't get your money back". You could also ask a retailer, " What's your return policy?" and they might say something like, "Ah, we accept returns within 30 days and you need to bring your receipt".
