CartHappy

Most grocery apps show you deals inside one store. CartHappy compares 350M prices a day across 10,000 stores, auto-applies every coupon, and splits your cart to whatever's cheapest that week. It can also learn your regular list and build your cart automatically — WXYZ Detroit tested it live on TV, saving a family $28 instantly. We built ours as an extension because it works horizontally, sitting inside each retailer's environment while helping the shopper shop across stores, not locked into one.
