What is CartHappy?

CartHappy automates grocery shopping by building a personalized weekly cart from your purchase history and comparing grocery prices across retailers. The browser extension integrates with retailer sites to display a pre-built cart and enable grocery price comparison and cart optimization based on price, availability, and coupons.

Users can also create carts manually on the site to compare products, find the cheapest groceries near them, and streamline recurring shopping. CartHappy applies coupon optimization and pre-approval workflows so shoppers review and complete checkout with fewer steps.
