As one of its daily deals, Groupon offers a $70 Vistaprint Credit for $17. That's $53 off and tied with our expired mention from six days ago as one of the best such deals we've seen for Vistaprint, although we saw the same credit offer plus 30% off regular-priced items in December. The voucher excludes shipping costs and sales tax; it expires May 15. Deal ends February 18.
