I just collect them for run mistakes.
I go to the bank and get probably 30 or 40 of them before I come to Vietnam. I hand them out to people that I know and friends. The people here consider the American $2 bill as lucky money. They will fold it and put it behind the clear cover on their cell phones. You would think you had given them a $100 bill, they are so happy.
