The costs for the SZ 05 and SZ 06 shirts were about $5.50 per shirt. That included the cost of shipping. Costs of the shirts were about $3.00 and printing was like $2.00 per shirt. Im sure parkedcar would have done the same this year. I had about 100 shirts shipped for the price of $50 or however much it was. Only ends up being an extra 50 cents per shirt when you break it down. Its better than having someone paying $7.00 for each shirt. Yes, we only had one design (although I could have ordered different colors I suppose if people let me know in advance) and we had to order a few more shirts to accomodate for late registering people, but at a cost of saving $15 per shirt compared to this year ($13 for shirt and $7 for shipping), that ends up cutting down a lot of the costs for the registration fee and allows tons more money for door prizes, nametags, and lanyards. If you want your best bang for the buck, go through parkedcar. He charged me absolutely nothing for the shirts. Whatever he payed to have them made, thats what he charged me. In return, all he asked was that he be a sponsor for SZ.
