Amazon just started a new promotion that gives 10% Cashback on select Alexa devices when you use either an Amazon Prime Visa or an Amazon Prime Store Card to pay for the purchase. These cards normally give 5% cashback, so this promotion adds an additional 5% savings. Eligible Alexa devices are listed here and include all of the Echo devices and the non-kids Fire tablets. Fire TV devices and third-party Alexa hardware are not included in this promotion. Since most of the eligible devices are already on sale right now, this is a pretty good opportunity to get some great deals. This 10% cashback promotion ends June 25th, but the sale prices will likely end this weekend.
