It depends on how heavy the letter is. If it is just a plain old regular letter it just needs one stamp.
The number of stamps is irrelevant. The cost is dictated by the weight of the letter and the method by which it is transported.
it will cost $8.50
1 stamp! unless its a big letter
1 first class stamp
it depends. if you want to send it signed post you will get two stamps if not normally one stamp.
Just one.... you can put 2 just to make sure that it gets there. That is if its just a letter
One first class stamp is all that's needed.
It takes three stamps to send a letter to Norway.
If you envelope weighs less than one ounce, it will take one forever stamp or one current first class stamp. If the letter and envelope weigh more than one ounce, the number of stamps will depend on the weight and the denomination of the stamps.
how many forever stamps = .94
1
3 stamps!
