Having trouble getting tickets to that pop concert you’ve wanted to attend? Even if you call TicketMaster the day tickets go on sale, it often seems impossible to score seats. Why? It’s the super-scalpers. They buy up as many tickets as they can, then scalp them for sale on EBay. The concert might be in Winnipeg, but the seller is in San Diego. Or Maine. And scalping laws don’t seem to slow things down.
