i buy from borders bookstore (retail, not online)
You can't beat the coupons they e-mail you for between 15% - 30% off books.... plus borders rewards is awesome and you earn $ for xmas spending
I live in Athens, GA and SIGH, most of the mom n' pop cool used booksellers are gone :( My favorite one was called 'blue moon books' it was a mix of old and new and of course the shop had a cat
Like twoleftneedles, I do not like Wal-Mart, and only have been in there once in the past few years
