COD = Cash on delivery. So basically the people that would receive the x-mas card would need to pay the 42 cents for the cost of the stamp in order to get the card. Plus, I'm not sure if I can request COD for 42 cents - especially for a stamp . anyone know? Reply:I'd send`em e-cards instead. I doubt you could ship christmas cards COD. I think it has to be something bigger and heavier since the postal service bills by weight. Reply:if you don't want to buy stamps then hand delivery them or don't send them.
