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. We compare. You save.
We compare the items you buy across all your grocery stores and always pick the lowest-priced match. When it leads to bigger savings, your cart may be split across stores.
