'6' T-Shirts

Most of you have probably already heard of the t-shirts being worn around the clubhouse with the number '6' on the front and the years 1997, 2003, and 2009 on the back. If not, read about it here:

The number "6"

Anyways, I was wondering if anybody knows if the team is going to be selling any of these to fans or if its just a clubhouse thing. I think it'd be pretty cool if they sold them to fans at the games.
