One of my favorite parts of Plaza Midwood. This is an awesome store with an awesome collection. Most of my experiences with used bookstores have just been shelves on shelves of books without any rhyme or reason to organization. Book Buyers actually has everything organized by genre, and even breaking down categories. (Instead of just "Military History" they'll have "WWI, WWII, Korea, etc.)
It's a dangerous place because I could A) spend hours in there, and B) spend so much money. The good news is that everything is priced so well you get an awesome bang for your buck. I randomly stopped by last week and walked out with four books in great condition for less than $20.
Could not recommend more!
