I am trying to mail a letter to South Korea. What and How many stamps should I use?

Question

It is a normal household. I want to send a relatively big packet, with a few letters and things inside. How many stamps would that take?
And what do you think the rough monetary cost will be?

Answer 1

You'll have to use a green form, available at the Post Office. The rate depends on the weight of the envelope, but just for example, the cheapest for 4 ounces would be $11.00.

you could always weigh the letter from royal mail site and it would give you a price,

Answer 3

Go to the USPS web site and they have the answer for you. If you don't know the exact weight of the package, just guess to get a rough idea of the price. Food scales are fairly accurate for small things if you have one.
