It usually works out to be cheaper to make your own mix at home especially if you hit up a place like Costco and buy all of your dry ingredients in bulk. You can just keep replenishing your mix over and over again instead of running out to buy a box when it's empty. This recipe yields 9 cups of mix and each cup yields an entire batch of pancakes. So you're getting 9 batches of pancakes from one jar of pancake mix!
