How It Works
1. Set up in seconds
For automation and personalization, download the CartHappy extension — it uses your purchase history to build a ready-to-go weekly cart. Prefer not to use the extension? No problem — you can shop manually on our site and compare products across retailers.
2. Shop your way
With the extension, your weekly cart appears automatically inside each retailer’s site. Without it, you can build your cart manually on our site and compare products across your favorite retailers.
3. Your cart is ready
We optimize across your stores (price + availability + coupons) and pre-build your cart. You approve and checkout.
