also - good deals on canned black olives, diced tomatoes, tomato paste etc.
oh, and if you like smoked salmon - over in the deli section there's some nice thin-sliced smoked salmon for an excellent price - try snipping some up into your breakfast eggs on the weekend.
speaking of which - you can get a large jar of capers at Costco for the same price or less than a super tiny jar at the supermarket

Also - their Kirkland brand men's button down, no-iron dress shirts are truly excellent - very high quality and look like $60 shirts, but cost around $17 at most (yes, I know, not food related, but these *are* good shirts)
Maranatha roasted almond butter - 1/3 the price compared to what you'd pay in health food stores or grocery stores - really good deal.
I know I'm forgetting stuff.
Hope this gives you a good start.
