Sadly, it's most likely Barnes & Noble Education since most universities have outsourced their bookstores to them. At least my university now offers free textbooks to students but Barnes & Noble Education runs the logistics of it.
When I was putting myself through school, I could never afford any of the textbooks. I pretty much lived in the school library for mid-terms and finals. It sucked. When most kids were studying at home, I'd have to camp out in the library because it's the only place that I had access to the textbooks. If a particular class didn't have their textbook available in the library then I couldn't take that class. This was before Bit Torrent, so piracy and PDFs weren't available options.
