How it works

We check the shelves every night.

Loonie records grocery prices at ten Ontario stores every night, keeps the whole history, and tells you whether today’s price is actually a good one.

Last checked Nov 11, 2:38 a.m. ET61,062 prices4,509 changed

Four steps, every night.

No guesses and no ads: just what each store’s website charged, recorded day after day.

  1. We check ten stores

    Overnight, Loonie searches 167 everyday items at each store, and records every price, sale and unit price it finds.

    Last night: 61,062 prices

  2. We keep only what changed

    If a price matches yesterday’s, Loonie just notes it’s still true. A new row is saved only when the price, sale or stock changes.

    Last night: 4,509 changes (7.4%)

  3. We compare with its history

    Each listing is measured against its own past at that store: its lowest and highest price, and its typical price, the middle of its daily recorded prices.

    Search for today’s prices cheapest first, open any item for its graph, and price your whole list in the basket.

What every label means.

The same labels you’ll see in search results and on product pages.

  1. Where it was recorded

    No FrillsVaughan

    Every price names its store and place. Prices can differ between locations.

  2. How today compares

    Lowest in 30 daysBelow typicalSteady priceAbove typical

    Against that listing’s last 30 days at the same store.

  3. The last 7 days

    One point per day. A gap means it wasn’t listed that day.

  4. Sales and deals

    Store sale · was $6.98Usually ~$4.28* · 32% off

    A sale is marked by the store. “Usually” is Loonie’s estimate for a deal the store didn’t label, from its own unit price.

  5. Unit price

    Compares different sizes fairly. Sort results by best value to rank by it.

  6. Same item or similar

    Another product codeSimilar for less

    Same item: a shared product code, or the same brand, name and size. Similar items are shown, never totalled.

Pick an item. Loonie finds a listing whose price moved recently and shows its working.

Questions people ask.

How often are prices updated?

Once a day. The check is scheduled overnight and usually finishes by mid-morning Eastern time. The last one finished Nov 11, 2:38 a.m. ET.

Which stores does Loonie check?

Loonie checks ten stores in Ontario: No Frills in Vaughan, Loblaws in Markham Bullock Drive, Zehrs in Uxbridge, Fortinos in North York Lawrence, Superstore in Toronto Gerry Fitzgerald, Loblaws in Toronto Carlton Street, No Frills in Toronto Shuter, No Frills in Toronto Front Street East, Superstore in Toronto Don Mills, Superstore in Toronto Weston Road. Prices differ between locations, even within one chain, which is why every price shows where it was recorded. Search, product pages and the basket show every store unless you choose to see only the stores near a postal code.

What does “typical price” mean?

The middle price when its recorded days are ordered from cheapest to most expensive. Prices that hold for weeks count more than a one-day sale.

How does Loonie know two listings are the same item?

Most national brands share a product code across these chains, and a shared code is the same item. When codes differ, Loonie only matches listings with the same brand, name and package size. Items that are merely alike are shown as similar, and never counted in basket totals.

Is Loonie free? What happens to my basket?

Yes, it’s free: an independent, non-commercial project with no accounts and no ads. Your basket is kept in a cookie in your own browser.

Where do the product photos come from?

From the stores themselves. Loonie keeps only a link to each photo, and your browser loads it straight from Loblaw’s image server, the one their own websites use. That server sees the request, as it would for any page that shows the photo. Nothing else about your visit is sent to it.

Why can’t I find an item?

Loonie only records what its 167 everyday searches turn up, so less common items can be missing. Try a simpler word, like yogurt instead of a brand name.
