The Kindle itself can hold thousands of books all in one 7-inch device. It has 8 GB of storage that will last for years, but if you’re worried about storage, you can simply un-download titles to free up space while keeping the book you paid for. The new generation of Kindle has a 6.8-inch reading display, meaning the borders are really thin. You can adjust the font boldness and size, and choose from reading displays that show where you are in the chapter and book. The glare-free screen looks almost paper-like, even in bright sunlight. And the brightness adjusts from white to amber in the dark to protect your eyes. Did I mention that it’s also waterproof for up to 60 minutes in fresh water, so you can read in the tub or by the pool? To buy: $95 (was $140); amazon.com. Other Kindle versions are also on sale, including the Kindle Oasis that’s $75 off, and the original Kindle for just $45. While the original Kindle is missing the waterproof protection and adjustable warmth, you can’t beat this 50 percent off discount. The black model has already sold out this morning, so the white one is sure to go fast, too. The Kindle Oasis, on the other hand, has everything the Paperwhite does, with a few added features. It has an ergonomic design, auto-rotating page orientation, cellular connectivity, and more accessibility settings that pair with Bluetooth, so you can listen to books, too. To buy: $45 (was $90); amazon.com. I would be remiss if I didn’t call out that all of these Kindles are available with a bonus deal: three months of a free Kindle Unlimited subscription. The subscription is like Netflix for books, giving you access to over two million titles, audiobooks, and up to three magazine subscriptions (like Real Simple, wink wink) for just $10 per month. If you’re an avid reader, the subscription is definitely worth the investment. To buy: $175 (was $250); amazon.com.
