This is a great alternative to the WSU Bookstore. You can nearly always get a better deal on your textbooks here. You are better off if you know the exact book that you need for a class - - sometimes there are problems with this bookstore carrying an older edition of a book when the newest edition is required for a class, but they do have a good return policy.
My suggestion, make a trip to the WSU bookstore, locate all of your textbooks there and note down all the info about them, then comparison shop here.
Parking is a problem. The store has a very small parking lot, where you must back out of your parking space onto Hillside near a busy intersection.
