I also must add as a buyer there is no better medium. To me the auction houses are better suited for the sellers...I see items routinely over sold. At any time I can go purchase just about any card ever made on Ebay in my underware at 2am. Tough to compete with that.
John, I basically agree with your argument regarding Ebay, but
you say that AHs are better suited for sellers and then when you sell you use Ebay (?). I would just add that many of us who frequent auction houses place bids at 2AM in our underwear (correct spelling

) or less

during those interminable extended bidding sessions. The fee structure on BST is unbeatable compared to Ebay or AHs but this is basically a prewar audience. Selling postwar cards on BST can work but frequently is like trying to sell beef in New Delhi.
