I had to check my wallet and I have seven of them in there.
My stash of them is running a little low and I got 30 of them when I cashed my check today.
The funnest recent use was when the Girl Scouts came to my door selling cookies. They were $4 a box. Good use for a $2 bill! When I paid the girls she got a weird look on her face and quickly went back to the Dad/chaperone pulling the wagon on the sidewalk and showed him. I couldn't hear what they were saying but watching was much fun.
