Amazon has put all Kindle models on sale for Black Friday. The regular Kindle is on sale for $49.99, which matches the lowest it has ever been in the past. The new Kindle Paperwhite released just a couple of months ago is on sale for the first time at $104.99, which is a savings of $35. If that’s too much, the previous generation Kindle Paperwhite is on sale for $89.99. Lastly, the Kindle Oasis, which hardly ever goes on sale, is down to $174.99. At $75 off its regular price of $249.99, that matches the lowest price it has ver been. Kindle Oasis deals usually don’t last for the entire Black Friday weekend, so be sure to order that one early if you’re interested.
