For those that are really creative; I think the following could be huge.

A marketplace where buyers post their "buy prices"; like the old Naxcom, in the grade desired, quantity wanted, etc. And than sellers click & can sell cards to them. Tracking is req'd. When a seller goes to sell a item, they are paid instantly or when package is accepted by PO via paypal. This would be great for all the set builders, etc. If the buyer isn't happy with the condition he can return item for refund. There would need to be securities put in place to prevent fraud. I don't think you can ever completely remove this element but you can prevent it and abuse.

FYI: Leon, I was thinking of this as new BST board too.
Break down posts by sport, year, etc. And people enter their needs and buy prices and so on.
