How many stamps...?

right now stamps are 0.41 cents a piece. Which I feel is a little high. so if you are sending it to canada I would say that is alot of stamps. If they sent you something pretty big with four stamps on it. and you are sending something with like 3 sheets of paper, I would say just to be on the safe side 3 or four stamps. But I am not for sure how much it would cost to send to canada. But it is 0.41 cents a stamp.
