I meant to post this earlier. I'm not sure if they'll still be in stock. Target has a nut-free (made in Canada) advent calendar this year.

LEGO makes advent calendars too. (food-free)
We have LEGO Friends, LEGO City, and LEGO Star Wars calendars at our house this year.
Update on the advent calendar: DD has gotten a bum calendar. It is missing several (including much of the past week) days' worth of candy.
That's so sad. All the effort to find a safe treat, and then for it to be a dud. ???
