Howdy all, I received in the mail the other day the sample photo's that they send out. The one I was really impressed with was their metallic paper. It seemed to make the colors jump off the photo. So my questions for the day are: Has anyone used mpix in general? Any positive or negative comments that you whish to share? And of course has any one used them and gotten prints done on the metallic paper? How did you like them? Worth the extra or just stick with the normal stuff? Thanks!
