Shoestring Deal Toothbrush and Case

This is one of the few items I love for the shoeboxes from Dollar Tree. 

Three brushes and Three cases $1

Not all locations carry but you can order by the case, 24 packages of three. You can have delivered to your local store to save shipping. If you don't need 72, maybe you can share with a friend.

I always worry that something like this won't be there next year when I need it   

When putting in a box, I take the brush out of the package and put it in it's case.
