This seems sort of anticlimactic, after all the great sales before Christmas, but if you didn't stock up on wrapping paper for next year already...this is the time to do it, at 50% off.
Walgreens sale starts Christmas Day at 9am.
I always like to get some fresh ornament hooks, and gift tags as well. This year I'm going to put a baggie full of ornament hooks in each of my Christmas storage boxes. That way I won't have to guess which box they are in next year.
