I ordered 7 prints from 40 by 40 down to 8 by 12. They were perfect. I have used shops in Vancouver because I was "worried" about using online printing services. The shops in Vancouver cost me around $200 for a 40 by 40. To be honest, I cant really tell a difference in quality. There is a slightly... very slightly... better quality in using the mom and pa shops in town, but not enough to justify the cost difference.
Also, yes, these guys are in the states. Yes, I was a little surprised. But wow, some of these reviews are from overally emotional people. I mean, at the end of the day, the prints arrived on time, no duty and are great quality. And what doesnt come from other countries... wow.
