The longest Prime Day ever is officially underway (through July 11) and as per usual, Amazon has discounted its own devices to some extreme lows. While we haven't been super impressed by the Echo deals, things like Kindles, Fire tablets, and Fire TVs are seeing their best prices ever by a long shot.

With these Wirecutter-approved picks under $100, you don’t have to spend a lot to get a good deal this Amazon Prime Day.

Amazon Prime Day is happening this week from July 8-July 11, but don’t get so focused on saving money that you forget to be careful.
