Thanks for the kind words, Aaron.
Your points are indeed valid and yes, ebay is a haven for crooks. If I bought an item that was described improperly, I'd be ticked off as well. BUT here we have a chip that is under-described, not specifically stated to be real or fake. Many other sellers of fantasy chips lie outright and that's how they make their livings- buying them at 79 cents apiece from the GGS and then putting them up on ebay as "chips from closed casinos." That constitutes fraud.
Josh also lists contact information: "To pay by phone or if you have any questions call us at..."
The fraudulent sellers tend to not list contact information in their auction listings.

The Osbournes have now become collectibles in their own right. Read the article in the link below to learn more about them.

Sellers should disclose...but by the same token, buyers need to do their homework.
