I did it! I put all the t-shirts on sale, paypal and mail order only (changing the credit card pricing is SOooooOoooooo complicated, didn't want to bother with it. Also, the credit card service chews huge profits off the top, so it isn't as good a deal for me, and it's as much work to change them all back... so.).
White shirts are all $3 off, dark shirts are all $2 off. That's t-shirts starting at $10. Great t-shirts, I might add. Really amazingly cool t-shirts, from all your favorite artists... who are still getting 100% of their fees!
You guys are the first to know. :) Order early! Order often!
