EBay was very helpful in selling items for my daughter's boutique. I buy frequently through them. Blanket condemnation of a useful business should be avoided.

But that is not what Deckman wishes to do- he is selling through Mudcat to raise money for Mudcat.
Foolstroop has a point. The normal postal channels are best unless the item has high value. I doubt that Deckman intends to sell books of $100 or more in value. Remember that normal US postal insurance does not extend outside US boundaries unless there is a specific agreement with the receiving country.
