Amazon has massive savings on over 800 books in what they are calling the Biggest Kindle Daily Deal of the Year. You can save up to 85% of regular prices with titles starting at $1.99. And, yes, there are still Kindles on sale today. The $50 Fire is sold out until December 24, but the Fire 6 HD is still available.
Amazon also is offering up to 40% off on its Kindle Unlimited subscription reading service. The longer you subscribe for, the more you save.
Barnes and Noble is offering 500 Nook books for under $5.
At Google Play Books, you can get up to 80% off select titles in their Cyber Weekend Deals.
Note that iBooks also has many books on sale for Cyber Monday, but they show in the iTunes app, not via the web browser. Sorry, but I can’t link directly to them. 😦
I am seeing a lot of the same titles on the various sites. This is a great “pick the store you like to shop at” sale!
