No, nobody is too late. I have 120 shirts on the way to my house, White w/ black, gray w/ black, and Navy w/ white.
I will be selling them at SZ, so look for me!!!!! cost is TBD still, but no way will I charge more than $15 for a t-shirt, prolly more in the $13 neighborhood.
For those not coming to SZ, you will still be able to order them by mail, I will post instructions shortly after I return from SZ. And don't worry, if we run out I will have more made.
