(CNN) - If you have mail to send out, get ready to shell out an extra penny.
Starting Sunday, first class stamps will now cost you 46 cents, while postcards prices go up to 33 cents.
Sending mail out of the country will cost you even more change.
International mailing will cost one dollar and 10 cents.
That's up from 85 cents to Canada and Mexico and a dollar and five cents to other international destinations.
