I did, I think they turned out pretty cute. It was easy to do, a good price, and they shipped really quickly. My only complaint was that in some of the pictures the skin looked a tiny bit orange, not horrible though.
Yes, I get free offers for them all the time. My calendar turned out great! I do like the quality of their work. : ) One time a photo book had a print error on one picture and they sent me a whole new book without having to send it back. I order from them all the time and I've only had to deal with that once.
