They don't always have all the books you need. They're prices are about $5-10 cheaper though. You have to make sure you show proof of dropping a class and your receipt within the first three weeks of a quarter if you want a refund. Some items such as study aids have no refunds.
The parking is absolutely horrible and so is getting in and out of there. I always forget that they do buyback, but it's probably because I always think of the parking when I remember the place. Not sure if they give better buyback prices. I forgot and should of checked it there before I sold a book I had to some other place. Might of gotten more. Oh well.
It's quite cramped and small. Again, parking is just horrible. Someone sometimes tries to direct you, but still I think it's horrible and dangerous.
