abebooks.com where they claim "Satisfaction Guaranteed". I ordered a book, only $4.42 where I was sent the incorrect copy. After asking them to correct it the policy is to send it back with tracking number. They want me to spend $3.99 to send it back and then I will have a net refund of 43 cents! As long as you pay for their mistakes then Satisfaction is Guaranteed! I got off with a cheap lesson on how bad abebooks.com is!
