I bought flour, chocolate chips and other baking supplies today at the grocery store, and -- with Christmas only days away -- they're on GREAT SALES right now. Today I was able to buy name-brand cheaper than store brand (and when it comes to certain baking items, I am picky -- having been a professional baker at one point, I can tell a difference). So I filled my cart. I have the storage space, they will be used in my house, and they won't be this cheap in the next few months.
Exception: Pecans. They're never cheap, so I'll just buy them when I actually need them.
