As a matter of fact, we have looked into it. There are two problems with the idea: 1 trying to get a decent quality polo at a price people would be willing to pay, and finding a polo that wasn't utterly boring or didn't make us look like vendors at a convention. We found some really nice red polos with black accents but never could find a way to buy them in bulk or at a price that would be reasonable. I would still love to do this if we could find a way to do it... but then... I am picky.
Just a note, we are always interested in any ideas you, the members, might have for new swag, shirts, etc.
