I took advantage of an eBay promotion and have 84 books up for auction on eBay. Since I didn't want to change my Buy It Now prices, the opening bid for each book is 30% lower than the Buy It Now price. This means that the books are on sale if you place the opening bid. While I occasionally get a bidding war, the vast majority of my books close at the opening bid price whenever I run an auction, so you have a good chance at getting a book at the lower price.

The auctions show up on the first and second pages.
Remember that I also have books up for sale on Bonanza.
