I've been there 3 times and left with a stack of books each time. They really do have great prices - waaaaaaaaaay less your typical book store. They are only there until August so I suggest everybody check it out.

As for selling your used books, how about half.com? I've sold books on there (especially text books) and it's been fairly easy. Type in the ISBN number and the condition of the book. It's super easy and if you already have an ebay account, you're already 1/2 way there.

Happy reading!
