Cool idea, agree with the comment about regrettable purchases so I think you need to figure something out for that.

I think there's a lot of space to apply game theory / gamification in e-commerce. Still need to get a clear understanding on the regulatory framework for this.

Also, which fulfillment service are you using?

Good luck!

I am fulfilling the orders myself (with help) via USPS and FedEx until it gets out of hand.

How are you handling the printing on these? Do you plan to buy in bulk and ship out once it ends or screen print the tees yourself?

The shirts are being water/discharged printed by http://forwardprinting.com. A very high quality and award winning printer.
