Canada

Few more places to consider if you're in lower mainland:
Freshco/Chalo if you have the option over Safeway/IGA (same stuff, cheaper, though produce isn't always super fresh).

Langley farm market for produce is great, often good deals and competes with big chains on prices on said produce, meat, not so much other stuff (again limited access depending on where exactly you live unfortunately).

I'd do Saveon only armed with price matching flyers or I'm after something very specific I can't find elsewhere. Plus I'm not a huge fan of Jim Patisson or whichever carguy owns it.

City avenue market is also pretty good for produce and the occasional offers for other stuff.

Very location specific - if you like a good bread, check out European bakery in Poco, awesome rye that would cost you 3times as much in some "artisan" bakery and still cheaper than semi decent loaf from big chains.
