TwoSmiles by HP cuts 15% off select gift cards via coupon code "SUMMER15". (Enter the coupon at price summary.) That's tied with last month's mention and among the best deals we've seen from this vendor, which offers print-at-home greeting and gift cards. (We saw a slightly stronger deal last Black Friday, which took 20% off a similar selection of cards.) It's valid only on Gap, Forever 21, Sports Authority, AMC Theaters, Bass Pro Shops, Toys "R" Us, Babies "R" Us, Aéropostale, Old Navy, Banana Republic, and Kohl's gift cards. Deal ends August 10.
