My favorite bookstore is Half Price Books and I am there quite often. In my own defense, I try to stick to the clearance section but it ends up being my downfall. How can anyone expect me to pass up books for $1? I just grab everything that looks good or is part of a series that I need. Other customers have actually come up to me in the store to ask questions. One guy actually said "Sorry, with all those books I figured you must work here." I don't actually buy everything I originally grab, I put some back. But I do take a picture of it with my phone so that I can add it to my TBR list on Goodreads.
