(KCEN) -- If you haven't stocked up on stamps, you might want to because the price of sending mail is going up.
The U.S. Postal Service is upping the cost of a stamp by a penny to 46 cents for a letter and 33 cents for a postcard.
The change takes effect this Sunday.
If it seems like the price of stamps just went up recently, you're right. It was one year ago this week when we saw the last one-cent bump.
