First of all, unless you want to get ripped off more than you ever have in your entire lifetime, do NOT sell them anything! They give you about 5 cents for every book. I brought in 2 huge boxes of many many books and they offered me $6. I was so upset I just took the flippin $6 and left. I've regretted that for a long time. You'd be better off donating them to a charity in need.
With that out of the way, Half Price Books is a good place to go if you don't want to pay full price for a new or used book. Even half price can be a bit expensive but if you really have to have something, coming here would be a good idea. They often have really great sales on all kinds of books which is awesome. They also have a huge record collection if you're into vinyl.
