All you can read

Amazon Kindle Unlimited

Not a member of Kindle Unlimited yet? Here's your chance. Get three months of Amazon's All-You-Can-Read buffet for just $1.99 total. The subscription service normally costs $9.99 a month, so you're saving $28 with this deal. After the three months are up, it will renew automatically for the normal rate. You can cancel at any time with no penalties for doing so. The deal is supposed to be restricted to people signing up for the first time, but the miles seem to vary on that.

$1.99 $29.97 $28 off

Kindle Unlimited gives you access to over a million titles, spanning from technical documents to cookbooks to fantasy novels to nonfiction. Need a self-help book? Want to re-read Harry Potter for the seventeenth time? It's all there, and it's all free with your membership. You don't need a Kindle to read, either. Amazon makes it easy to read thanks to its free Kindle reading apps for iOS, Android, PC, and Mac.

You can keep up to ten titles at a time, and when you feel like swapping them out, the process is seamless. I'm always shocked at the wide variety of available options. More than a dozen times, I've gone to purchase a Thrifter Kindle book deal, only to find that the title in question is already free thanks to Kindle Unlimited. You can take advantage of thousands of audiobooks, too, if you want to spice up your commute or listen while you cook and clean. The options are almost endless.

Popular choice: Bose QuietComfort 35 II Wireless Headphones

The Bose QuietComfort 35 II wireless headphones are down to $299 on Amazon. Bose is very particular about dropping the price on headphones like this. The deals are rare and hard to come by. We've only seen them go on sale once before this year and it was brief. The last sale before that was around the holidays last year. These headphones have active noise-cancellation you can adjust based on where you are, Bose quality sound, Bluetooth, NFC, and up to 20 hours of wireless play time. The active noise-canceling will last up to 40 hours if you choose wired listening. They have a noise-rejecting dual-microphone system that allows you to receive phone calls and use the built-in Alexa functionality, plus Bose AR tech. The $50 discount applies to all three colors so you can take your pick.
