How many BIG shows have you attended? How do you know they were on eBay? They could have been using an app on their iPhone. Chris
The N.O.W. and Central Wisconsin Coin Assocation (I think I have the name right), not "BIG" as some but it made me very intrigued. And how I know they looked on Ebay is because they shows the completed auctions on their phones, an app and the Ebay website are very different so no confusing the two.
