Amazon's Kindle Paperwhite is on sale for Prime Day for $134.99, a 10% drop-off from the full price of $149.99. That $15 drop pales in comparison to last year's Prime Day sale, which saw the same device go for $55 off.

But right now, it’s on sale for Amazon Prime Day—a major deal, considering the Paperwhite’s price has only dropped two times this year so far. That means now is absolutely the best time to shop, while it’s still in stock.

Amazon Prime Day is happening now and, as usual, Kindle e-readers are on sale. But which model is the best? And how can you get a better-than-Prime-Day deal?
