Amazon offers cashback rewards if you scan receipts through its Alexa app

Alexa has introduced "Shopping List Savings" to the Alexa App, letting you scan receipts on eligible products from any store to gain cashback rewards, TechCrunch reported. It won't cost you a thing to use it and you'll get cash back to your Amazon gift card to use on any item on Amazon. The catch is that the system will provide Amazon with a ton of valuable data on your shopping habits, even when you're not shopping on its site.
