I was thinking more about what else I could do to prepare. When I go grocery shopping, I'm going to start picking up all those wee non-perishable extras that you buy, like cranberry sauce and so on. One or two a week thrown in with the rest of the groceries won't be so painful on the purse strings as the usual festive run. It'll be pretty soon that the cookie tins etc start appearing on the shelves too.
I've designated a cupboard in the kitchen for it all to go in and no one will be allowed to touch anything in it, otherwise it defeats the purpose. You could just as easily use a big cardboard box in the garage or closet if you don't have kitchen cupboard space. Seeing that build up alone will be an incentive for me to keep it all under control as much as possible.

I'm getting into this idea!
