If you haven’t heard of them yet, then allow me to do a brief introduction:
ArtyBuzz is a UK based artists’ community for showcasing your art and selling canvas prints, Giclees, t-shirts and more. The company handles all the product and shipping; think Zazzle, but more artsy and more about community.
Right now they’re running a t-shirt contest for existing (and new) members with a chance to win credit from the site (use it to pick up some awesome artwork) and props via the site, blog and twitter.
Popculturetees.com t-shirt blog. Also, look for new coupons, discounts, & promo codes!
