IUB is the easiest and best place to go to get your textbooks. They always have the right books for the right classes, labeled and organized in a way that makes sense. It can get a little crowded, but what bookstore doesn't at the beginning of each semester. They also carry nontextbooks and have a pretty good selection, along with apparel, calendars, posters, school supplies, etc. What I always loved was that they do free gift wrapping at Christmastime, which is so great if you have Illini fans in the family. The prices are a little high, but it's worth it at this store!
