I have had the experience now two times of ordering a textbook on AbeBooks, but receiving the wrong edition. In the first instance I ordered a calculus textbook but received the solutions manual for it instead. In the second instance, I ordered the 4th and most current edition of a biology textbook, but received the 3rd instead. With the calculus book, it cost more money to ship it back for a return than I paid for it, so essentially I just lost my money. I am sending back the biology book and hoping I will get my refund as it cost me almost $170 with the postage and tax, but I will only get back what I paid for the book. I strongly advise against trying to save money on textbooks by using AbeBooks instead of your school bookstore/publisher. The sad part is, AbeBooks used to be a very reliable place for buying books (I was a customer for years), and I can only think it went downhill after being taken over by Amazon.
