Amazon has just put its all-new Fire 7 tablet on sale for $44.99, which is 20% off its regular price of $59.99. This tablet was just released two months ago and has never been on sale before today. Also on sale for just $5 more, and probably a better buy for most people, is the Fire HD 8 for $49.99. While the Fire 7 has the same processor and 2 GB of RAM as the Fire HD 8, the larger tablet has twice the storage, longer battery life, and a slightly better screen. If you want an even better experience, you can get the Fire HD 10 for $99.99, which is 33% off its regular price of $149.99. With it, you get an even better screen, 3 GB of RAM, and an even better processor. These deals, as well as all the Fire TV devices currently on sale, are part of Amazon’s big Back-to-School sale.
