Does anyone know how much Pin Trading adds to Disney's bottom line? Is it a *huge* revenue generator for Disney or something that they simply added to enhance the Disney experience?

I'm coming in January with just under 100 pins for trading...I'm looking to have fun with it.

DS-12 is into Goofy pins, though he was excited to find a complete set of buses last year. I think I will concentrate on Monorail, Muppets and perhaps a few hidden mickey pins this time around.
