Groupon offers a $70 Vistaprint Credit for $17. Plus, receive 50% off regular-priced items via this offer. (The discounted items can be found here.) That beats our expired mention from four days ago (which had 30% off regular-priced items), is $53 off, and among the best such deals we've seen for Vistaprint in recent weeks. The voucher excludes shipping costs and sales tax. (Orders of $95 or more qualify for free shipping.) Deal ends October 11 at 12:10 am ET. The credit is valid until January 2.
