That'll get you cash directly on your Amazon gift card, usually in 24-48 hours, which can be used to buy anything on Amazon.Īmazon doesn't explain how your data will be used or promise to anonymize it, as TechCrunch notes. You can shop the offers at your 'go-to grocery store' (or pharmacy, or any store where you can get an itemized receipt) and scan the receipt and product barcodes to redeem them. You just search the Alexa app to find available offers, then add them to your shopping list. 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. 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. 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.
