There is one blog that I visit sometimes which always promotes books from www.becksbooks.com. The blogger is from one of the groups where I am an active member as well. That's why when I see the Becks Books, it immediately reminds me of that specific blog. Anyway, at Becks Books, you can rent, buy, or sell textbooks. This is what my husband used to do to save money in buying his books when he went back to school.
