The value of the stamps is just as important as the number of stamps also. Stamps come in all kinds of values: 1 cent, 5 cents, 41 cents, 75 cents, etc…

You can always go to www.USPS.com and look up the letter and pkg guidelines so that your mail wont be returned.

GOOD LUCK!

Letters cost different amounts – depending on how heavy they are – where their going – whether they are normal or express – whether surface mail or airmail.

If you do not know how much the stamps to put on are – go to your post office and they will tell you and sell you the stamp(s) – which may be one , two, three or more to make up the correct value for your letter.

**

If your letter is heavier than normal, have it weighed at the post office or a mail store to see how much postage you need on it.

In the US postage is 41 cents, PER OUNCE.

Using an old 39 cent stamp, a two cent stamp must be added.

Any more than that is overpaying.

An ordinary letter is less than an ounce. If weight is added, it must be weighed.
