Moo.com knows a thing or two about business. They know that if they give out quality freebies, they'll attract a bunch of customers. I got 20 postcards made of 7-8 different art/images I've made, completely free. Although it took a while for them to arrive (they're a UK company), I love them. The images are clear and the paper is glossy and crisp. They make my images look very sexy. And for about a buck per card (plus shipping, blah), I can undoubtedly see myself getting some more made. Well done, moo.
