I stumbled upon this site in my travels earlier this afternoon -
Custom T-Shirts by T-Shirtmonster - Custom T-Shirt Printer
I searched these forums extensively to see if anyone had made a comment about this site, but was unable to find one. From what I can tell, it's fairly new and seems to be a blend of design competitions and a print-to-order fufillment service. I'm unaware of any sites that are of this style if they exist, so it's new to me. And I think I like it a lot.
Doesn't look like much traffic as of yet (very few designs in the monthly competition, considering the $1000 cash prize). I'll be watching this site to see how it performs.
What does everyone else think?
