The yellow jersey was a limited run. We're not one of the big markets, so Adidas gave RSL a limited supply of the jerseys to sell. IIRC, it was somewhere between 100-150 jerseys, and they were gone before the game started on the day they were made available. They were authentic jerseys, so they were sold around $75 each, so they had to have made some money on them. Trey Fitzgerald talked about this at the beginning of the season. He said that Adidas only gives them a certain number of kits each year, and if they need extras they pay for them. Basically, he said they have to make each kit last two games. I wonder if that's different for other teams in MLS.
