At dawn this morning, New York Giants fans were already out hunting for merchandise to help them savor their victory over the Patriots. By the time the BPP arrived at Modell's sporting goods store around 10am, Giants hats were already sold out. Check out the scene for yourself.
Obviously in order to get championship goods on sale less than eight hours after a game ends, you have to print up items with both teams' names on them way before the game. So what happens to all the "Patriots Super Bowl Champions" t-shirts and hats that are sitting in a warehouse somewhere? This might give you some idea.
