i just recently ordered a shirt and it was 500 rewards points. I have a friend who recently got his first shirt from them and was very pleased with the fabric/feel of the shirts.
you can't beat getting a free custom made shirt for about 25 minutes of your time (200 points for adding a "created" shirt to your cart, and referring yourself (i did 6 or 7 other email addresses of mine, and i think they track the IP Address or something, but worked out perfectly when i logged in and signed up for each on my iPhone using the safari private browsing feature)...will update when I get the shirt but already got the confirmation number etc...
