Book Buying Spree!

So, tomorrow I get 40% off books at Barnes and Noble.  Now, I usually buy from used book stores so what do you guys think is a must have that probably won't show up in the used bookstore?

Yeah, I already have all of Wot and the Dark Tower... they're actually piled on my dresser in an interpretation of book janga.

I ended up getting some Murakami, Wind-up Bird Chronicle and Hard-boiled Wonderland.  I also picked up Look at the Birdie, Vonnegut's unpublished short fiction. Sue Grafton was there when I went shopping too!
