I realize this is terribly uncool, but I love the dollar store for things like this. I mean we got some pretty good decorations for just $1, and a lot of them will probably get reused next year. Even the ones that don't (like the static cling pumpkin my kitten has been pretty persistent in insisting should not stay hanging on our window) well, they were a dollar. I also got all my Halloween party plates, cups, napkins, straws, table cloths, candy bowls, and platters from the dollar store, which would have been scarily, creepily, frighteningly expensive had I gone to iParty or Target.
I can't wait to go back for Christmas decorations!! Maybe I can afford enough things to make my car more festive than this guy's:
