Groupon offers a MetalPixs 11x14" Metal Print for $39 or a MetalPixs 16x20" Metal Print for $49, each with free shipping. That's at least $65 off and tied with last month's mention as the best deal we could find from MetalPixs, which prints uploaded photos onto aluminum. This deal expires Feb 7 at 1 am ET; the coupon will be valid for redemption between February 9 and May 9.
