We ducked into this SAQ when we were walking around the city, just to browse the selection a bit. They have a fairly extensive selection of alcohol but their prices are ridiculous. With a quick google search, you'll realize that most of their bottles are insanely overpriced. I guess if you're trying to hunt down a particular brand of ice wine or something and needed it for a gift, this would be a convenient place to hit up. Otherwise, I don't see why anyone would purchase alcohol at such unfairly steep prices. It's probably mainly a store for tourists looking for souvenirs.
