Built for Atlantic Canadians
tired of guessing at the checkout
CartWatch exists because grocery prices vary more than most people realize across Atlantic Canada, and there was no simple way to know where your weekly shop would cost the least.
Like most Canadians, I watched the cost of living climb steadily higher, rent, fuel, utilities, and yes, groceries. It's not just inflation in the abstract. It's the moment at the checkout when the total is higher than you expected, again. Realizing that the same cart of groceries costs meaningfully more than it did two years ago, and that nobody seems to be helping you do anything about it.
I built CartWatch because I got tired of guessing. Prices at Sobeys, Atlantic Superstore, and Walmart vary more than most people realize, sometimes by dollars on a single item, and there was no simple way to know where your weekly shop would cost the least without driving to three stores and comparing by hand.
CartWatch does that work for you. Prices are updated nightly across all three major grocery chains in Atlantic Canada, so you always know where to get the best deal on your weekly essentials. Whether you want to do a single one-stop shop at the cheapest store, or split your trip to maximize savings, CartWatch shows you exactly what you'll spend before you leave the house.
