$0.00 Priced Sweatshirt in the Rose Garden

Ok, there is this white sweatshirt in the Rose Garden that has red, buff and green 3 layer letters. The cost for it always says $0.00. Does anyone know what the deal is with it. I like it since it is hooded and on the plain side, but has all our colors.
I am sure it must cost something, but can't get on the site to email them about it.
