Hey Product Hunt! We ve just updated CartHappy to help you find grocery savings right on a store s search results page. Check it out here: Instagram Demo
Previously, you needed to open a product or add it to your cart before CartHappy showed you potential savings. Now, you can see them while you browse. Search for something like milk on a supported retailer s website, and CartHappy shows you which products are cheaper at another store - and which are already the best price at the site you're on.
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.
