WASHINGTON (AP) â It's going to cost you a few pennies more to mail a letter. The cost of a first-class postage stamp is now 49 cents â 3 cents more than before. Regulators approved the price hike in December, and it went into effect Sunday.
Now for the bad news: USPS also increased domestic stamp prices, the AP reported. As of Jan. 27, regular domestic letters weighing one ounce or less now cost 46 cents to mail, a one-cent increase. Each additional ounce costs another 20 cents. A domestic postcard stamp has risen to 33 cents.
