How it works
Tell it who you feed. Get the whole plan and a priced cart.
- Sized to every person. A 16-year-old and a 12-year-old don’t eat the same plate.
- Priced at a real store. Every line is the store’s own shelf price, with the date it was read.
- Compared with the average. Each item against the Canadian average, so you see a good price.
- Save 10–30% on your family’s groceries.
- Budget-friendly carts built across every grocery brand.
- Healthy portions for everyone, and fewer junk-food impulse buys.
- Compare prices across grocery brands, item by item.
- Build a real cart and pay online for pickup or delivery.
