It is a bit hit and miss around pricing and availability.
I think if you rewound the clock 15+ years ago it was a lot more in your face with great deals on Dujac, Jamet, and more just sitting on store shelves. I imagine that’s where this reputation came from.
These days I think there are great wines to be found at good prices, but just not as readily obvious. You could walk into one store and find some really attractive wines at good prices, and other and find it quite ordinary or overpriced.
A lot of the the really rare stuff at good prices hits their lottery system, where they do a few releases per year. To participate you need to use an account online and make entries for the bottles you’d like, and then they do random draws for those. the downside is your rarely get allocated much. The upside is that when you do, you get a great wine at a great price.
Besides that, the SAQ does an online release weekly on Thursday mornings where ~150 wines become available for online purchase with free delivery to any store. Most of inventory will eventually ship to stores to restock inventory, but the more sought after stuff sells online within minutes. A recent example is Burlotto’s base Barolo from 2021 for IIRC ~$80 CAD. All bottles sold online in around 10 minutes.
So it’s extremely unusual these days to come across anything very allocated like Allemand, Gonon, Rougeard, Rayas, Burlotto, Ravenau, Roulot, or Rousseau sitting on the store shelves, despite it selling at the SAQ.
If you dine around the city, you may find some of these producers on wine lists at reasonable prices (around retail market price). Quite the bargains when you can find them considering you’re at a restaurant.
If I were generalizing about where the best retail bargains are at the SAQ these days, I’d guess Italian wine. Especially compared to US retail. It seems like the SAQ can at times be 20%-30% less.
And lastly, I had a chuckle when you asked which currency their prices are in. It’s a retailer that exclusively serves Canadians, of course its in CAD. Seems your American was showing.
Taxes are included in the purchase price and online orders to a store aren’t charged shipping. When you factor that in, I find prices are often quite good/fair.
