I saw those at my store the other day, close to the Halloween costumes. Not sure if they're intended to be given to trick or treaters or what, but a great deal!
I just bought similar puzzles at the dollar store for my 4 year olds party favor bags and they were a hit. That's a great deal!
We did the same.
Tip for anyone who may keep these for their kids...the first time you open them, put a number on the back of all of the pieces so when (not if) you find a random piece around the house, you'll quickly know which puzzle it is. Someone gave my oldest 8 100 piece puzzles that were all in one poorly divided box. Terrible idea, but we put them together, labeled them, then put them in ziplock bags. Now it's tolerable.
