I bought 100 Years of Solitude on APGIL's recommendation and his recommendations are usually pretty right on (In Cold Blood notwithstanding), so I have high hopes for it. And I've been wanting to read something by Neil Gaiman for a while so I figured this was a good opportunity.
They also had a compilation of Mark Twain novels (the most prominently featured being Huck Finn, one of my favorites), but it wasn't half price so I didn't pick it up.
