Okay, sometimes I want to buy a book at Amazon and I find that it is too expensive. So I look at the used copies they have available. Sometimes these copies are a good price, and I pay the extra $3.99 in shipping and I'm good to go. Other times the used price of a book is listed at some ridiculous rate like $130.00! Really! I'm assuming they don't want to sell the book at all!
Why does Amazon allow this?
