OCD Girl Scout

Ok, so I'm a little OCD.
I like to call it "being prepared",

I was once a Girl Scout, ya know!

(We order a pre-cooked, smoked Turkey, so we must buy broth.)

I love the fact that many stores are going to be closed on Thanksgiving.  I never (and have never) shopped on Thanksgiving, or the day after, for that matter.  Not judging anyone, just saying that I  like the idea of people getting to spend their holiday time as they want.  However, it seems that every year there is something that I must send Mister to the store for early on Thanksgiving Day - something I've forgotten.  I hate it but I do it.  This year I'm trying to label things to avoid this holiday blunder.

What about you?
Is there something that usually requires a last minute run to the store?  If so, what?  (You're among friends, so you can tell us.)  

To answer my own question - extra ICE is one of the common things I forget.
