There some left mostly in medium, large, and XL. Check them out in the store:

If you want to order one, message me with what you want and I'll let you know if I have it. Otherwise if you place an order and I don't have it, I'll have to send a refund. The shopping cart does not manage inventory. It's been on my to-do list for a long time, but I haven't gotten to it.
I'm thinking we should do another shirt sale soon with a new design.
