They have individually packed bags of jerky. It tastes good. It's a little sweeter than I like, but good for the price.
Olive Oil. Canola Oil.
Tuna. Canned salmon. Smoked salmon.
Fish oil caps. Flax oil caps (if you're so inclined (I'm not))
They have huge bags of spinach for very little money. Bell peppers are cheap, too. The whole veggie section is good, as long as your eating a lot of veggies.
Cottage cheese is cheap there, provided you like that brand and can deal with the big tubs.
Eggs are VERY cheap. Good for all the egg whites, and cheap enough to not feel guilty about tossing the yolks.
