Groupon offers a Picture It On Canvas 11" x 14" Metal Print for $39 or a Picture It On Canvas 16" x 20" Metal Print for $49, each with free shipping. That's $104 and $154 off, respectively, and tied with our mention from two weeks ago as some of the best aluminum prints deals we've seen. (We saw the 16" x 20" print offered for $10 less last month.) The voucher expires May 1; deal ends February 2.
