Unfortunately, I can't give less than a 1 star rating, but a lower rating is richly deserved. I ordered a book from Alibris a couple months ago. The day after placing the order, I received a notice that it had been shipped. A month later, it still hadn't arrived, so I contacted the seller through Alibris. After several days, no reply, so I contacted Alibris. They said they would contact the seller. I still got no reply, so I contacted Alibris and was told a refund would be processed and to allow 3 to 4 days for it to appear in my Paypal account. After 10 days, it still isn't there. I emailed Alibris - again!
As far as I can tell, Alibris is just a money collecting agency under the guise of a book dealer. Avoid at all costs! A lower price is no bargain when you don't receive what you ordered.
