Excuse me. What's the postage on this letter to New York, please?
How would you like to send it?
By registered airmail.
Eighty cents, please. And please write down the postal code in the mailing address. Anything else?
Yes. I'd like 6 postcards and 10 fifty-cent stamps, please.
All right. Here you are.
And this package is for London. Will you weigh it for me?
Yes, of course. This package is 10 grams overweight. You'll have to pay 50 cents extra for the overweight.
