There is a girl in one of my classes who sent out a flyer giving a 5% discount on purchasing textbooks OR selling them back. I ordered my book on Sunday & received them today for only $5.99 in shipping. Oh yeah...and the new book (without the discount) was $70 cheaper than it was in my bookstore.
For anyone who is looking to sell back their textbooks (you'll have to check their site for more details but they offer free shipping & show you what they'll pay based on condition) or buy textbooks for next semester/quarter/mini-session...check it out.
