How hard do you think it will be to get all ten? Will they give out 2-3 different ones each week? Any clue? The promo runs from 11/17-12/14 so that is like four weeks.
My local McDonald's also sold me all 10 without food for $2 each. But it seems like not all McDonald's have all of them at once, or have a rule that they can only open one box at a time.
