Living Social offers a $30 ProFlowers Credit for $15. That's tied with our February mention as the best ProFlowers credit deal we've seen. Plus, unlike our last mention, it can be used towards shipping (which starts at $12.99) and sales tax, which is added where applicable. The entire credit must be used in a single order and cannot be combined with other coupons. The deal ends May 7 and the credit must be redeemed before July 31.
