Do you keep your decorations in family inventory or rebuy each holiday?

I like the decorations box to rummage for freebies, put up lights and take them down after the Holiday. Sometimes I'll keep a rummaged decoration if I like it, but usually sell most of them. I don't abuse rummaging though, only do it once. So, I mostly just keep the decorations box in the household's inventory and bring it out for any Holidays my Sims celebrate.

EDIT: BTW Happy Thanksgiving to all my fellow U.S. Simmers! *gobblegobble*
