The newest site I’ve heard about to find many of your favorite store’s weekly flyers is www.flyercity.ca. The emphasis is on stores across Canada but there are some here in Montreal.
They advertised that they have: Toys r Us, President’s Choice, Rona, Dell, Home Depot, the Brick, Giant Tiger, de Serres, Sears and Mark’s (L’Equippeur) but I couldn’t find all those when I looked. Across the country, there’s Black’s, Sportchek, Henry’s, Napa Auto Parks, PetSmart and Vistek.
There’s a cute feature where you can shop by discount amount. If you only want to buy stuff that is, let’s say, 50% off, it will highlight only those items.
