Amazon is sweetening the deals on their hardware by offering 10% Cashback on Amazon Devices when you use either an Amazon Prime Rewards Visa or an Amazon Prime Store Card at checkout. Pretty much all of Amazon’s devices are included in this offer, which you can see a list of here. This includes all Fire TV devices, making the Amazon Fire TV Stick 4K just $31.49, and all Echo devices, making the Echo Dot 3 just $21.60. To verify that you’re earning the additional cashback, look for a link that reads “items with additional rewards” next to your payment method during checkout. There you’ll find a list of items receiving the extra discount. The cashback reward will appear on your card statement, not as a discount at checkout. This promotion ends Nov. 26th.
