Papa Media & Alibris are SCAM ARTISTS! I searched Alibris for a particular book using an ISBN (International Standard Book Number), which is specific to *ONE* book only. The Alibris search engine delivered something else. I didn't notice the error until after I paid. I immediately notified Alibris & Papa Media of the error - within *FIVE* MINUTES. They REFUSED to cancel! In order to get a refund, I had to contact my credit card company. Papa Media has such poor rating on Alibris, they have opted out of buyers being able to read it! That should have been a red light!
