This used bookstore is impossible to navigate, and even as an experienced thrift shopper, I really cannot stand it. The books are in piles on the floor throughout the store, and there are no section headings or any kind of categorizing system, whatsoever.
Granted, for any good thrifting experience, you have to take your time and really hunt for a bargain. However, there are no bargains to be had hear. Despite the twin cities of Urbana-Champaign being a college town and bursting at the seams with academics, it does not seem that many sell their used or unwanted texts here. There is just a lot of nonsense between these stacks. This also suggests to me that perhaps they do not buy books for reasonable amounts, while I would say that comparably they overcharge for the generally very damaged fare.
If you are looking to buy or sell used books in the Urbana-Champaign area, I would highly recommend the Jane Addams Book Shop (www.janeaddamsbooks.com). They have a huge selection--three whole floors--which are clearly organized, provides an extensive leisure and academic assortment, and everything is a bargain buy. This is all not to mention the extremely helpful service of the new ownership, something that cannot be said of Priceless Books.
