I buy from half.com almost all of the time that I buy books online. Sometimes I buy from amazon but I prefer to buy from half because I'm an affiliate so I get a small commission from my purchases. This last time I bought things though, I bought three from one seller (because you get a good discount on shipping if you buy from the same seller) and they only shipped one, but said they shipped all three. I had to wait three weeks before I could claim the items not received (none showed up for weeks). Then finally the one item that was shipped (the seller said he shipped all three) arrived with a note that the other two were out of stock. Then the seller said oops and refunded those two purchases, but I was kind of ticked. This was a seller with over 10,000 feedbacks. Usually I try to stick to small sellers because they seem to have a better handle on their inventory. But other than this last time, I have had lots of good buys on half.com. I always bought my textbooks on half. Jamie in Michigan Currently Reading - Chocolate Chip Cookie Murder by Joanna Fluke
