I was at Vitamin Shoppe earlier and they had a charitable promotion going on. The promotion was for "Operation 20/20", a program which distributes Vitamin A to children in poor areas in order to prevent blindness. If you donated five dollars, you donated enough to help 20 children and you also received a bracelet. I went ahead with this as it seems like a great cause.
The parent organization for Operation 20/20, Vitamin Angels, operates five different programs to help people in need.
