Every single Kindle device gives you access to the Kindle Store, you just need to sign in with your Amazon account to access it. The Kindle Store is a great place to purchase titles from, and they're typically cheaper than other online bookstores too. We've got a handy guide to how to buy books on Kindle too. If you happen to be a Prime member or have an existing subscription to Kindle Unlimited, you can access them both directly from any of the Kindles. In fact, all the current Kindle models have Bluetooth connectivity and, if you have an Audible account, you can listen to audiobooks too via pair of wireless headphones. Better yet, Kindle users in the US can take advantage of borrowing from a local library if you already have a card. You'll be able to browse their digital catalog on the Kindle and borrow ebooks or magazines. You can also sideload ebooks from an existing library you might have, but you will need to make sure that the file format is natively supported. Read more about how to send an ebook to Kindle.
