I have experience using eFollett because this was the online company of choice that my university used to offer their textbooks. Because of this (going through the university) the prices were much more expensive than buying them from other websites that offered peer to peer selling/buying. The plus side of eFollett though, is that if my university could trust them, I too felt like it was a company that I trusted. The site is easy to access and easy enough to navigate. I have mostly only used this site in regards to getting textbooks, and they have almost always had what I needed, unless it was some kind of a special edition (which some professors tend to do). And I don't know if this is for all colleges who go through eFollett, but the site always offered other merchandise such as school apparel and other gifts that one would find in the campus bookstore. I don't know if the prices were any better than what they were on campus, but for the apparel they were decently priced online.
