Glad you're not having problems.
I hope to benefit from other's experience, and share my own. A perfect store for me would:
1) have stuff like Brisket, Tri-Tip, Boston Butts in stock
2) be nearby
3) have fair/good prices. Why is brisket $4 / lb, when a Grade AA rib-eye is also $4 / lb.
I think the scarcity is the result of a couple things. Some of it is inexperience - I'm relatively new to this, and I have to change where I shop. Less Grocery stores, more butchers & ethnic shops.
Many Grocery stores stock the retail cuts only (ground beef, steaks and small roasts). I've not had a positive / informed experiences when I asked the meat counter clerks or their supervisors at the grocery stores - sometimes I seemed to know more about the topic then them, even when I used the official Canada food agency terms. Maybe your grocer experience is different.
Some of it is location. Big cities have more choices, but are sometimes hard to locate &/or access. You may have to visit a quite a few stores before finding one that suits. In Toronto, the better ones I've found were well off the beaten path (industrial areas).
With city traffic thats a lot of Saturdays to invest in searching for a butcher.
