I had mentioned this in a previous post. Sorry I don't know how to link to it.
I agree with the previous post recommending IGA. For booze ,pop, bottled, frozen and dry items I use CK's. The only way I can describe the location is as you come off the airport highway and then take your left at the roundabout to go to IGA... CK is on your immediate left. Blue building as I recall. It is setup like a small Costco... No glam. Enjoy.
