Please protect yourself from the following SCAM

Two of our advertisers have informed us that they were subjected to the fraud attempt described below. This is most likely to occur if you have a large item for sale or if you are selling a large lot of books.

There are probably other variations of this scheme.
BE SURE TO PROTECT YOURSELF - make certain any check you receive is valid, and avoid sending any money to a shipping agent (if a buyer can send money to you, he can also send it to a shipping agent)..
