bulk baby

I had a duh moment the other day...why buy expensive, yet oh so convenient, cute containers of yogurt, when I can buy larger containers of the same thing for less and then place them in small Tupperware containers for lunches.  And why cook five servings of spaghetti sauce when I can cook 10 servings so we have leftovers?

Soooo....now I'm buying the following in large-in-charge quantities:  applesauce, spaghetti sauce, almonds, trail mix, cold cereal, graham crackers, baked fish crackers and yogurt.  What do you buy in bulk or in large quantities?
