Stamps and mailing?

Question

how many stamps would i need if i was sending mail to the UK from the US?

it's just going to be a card.. it's not a package or anything.

Answer 1

NOTE: Your card WILL NOT make it to UK by Christmas. If you wish for it to arrive by Christmas, you will have to use Express delivery as package. (Not Standard)

But, if your friends don't mind it late, you may send it.

IT will cost .90 if it is one ounce or less.

(Three .41 or First Class Stamp)

You can go to the post office and pay the clerk for exact amount if you wish.

If it is square envelope (ie: 5"X5" or 7.5" X 7.5") has an uneven thickness, or has strings or clasps to close envelope, add .17 in addition.

If your card is two ounces or less, the postage is $1.80, and $2.70 for three ounces. Also write, stamp, or place a label that says "Air Mail" on the envelope.
