$9.99 per book may not sound like a bargain to us who troll this subforum of bargains and such, but for academic publisher Palgrave Macmillan's books it is. Skimming over some of their selection, I rather quickly saw one with a list price tag of $134.99, for example.
The sale includes both paper-based books and ebooks. Unfortunately, I did not find a way to exclude the tomes that were available in paper-based form only (if you're interested in paper-based books, you will be happy to know that shipping for them is free during this sale!). It appears that the total number of books in the sale comes to 31,575. It would be a daunting task to skim over all of those, of course, but thankfully the books are organized into a couple of dozen or so broad categories, and there is also a typical search function to help us.
The sale lasts through Dec. 3.
