Instead of buying primarily olive oil for the kitchen, buy a vegetable oil in bulk and use that for most of your cooking. The 'extra' bottle of olive oil will last longer and you won't have to spend as much. I used to use olive oil for pretty much everything and then buy butter for baking. This saves me cash!
