The United States Postal Service is once again charging more for stamps and postcard mailings.

Beginning Jan. 27, the price of first-class domestic Forever stamps went up a penny to 46 cents. Post cards now cost 33 cents to send.

Even with the increase, the post office is still struggling financially.

Last January, the agency, which depends on revenue from the sale of stamps and other products to fund its operations, raised stamp prices from 44 cents to 45 cents.
    
According to Post Master General Patrick Donahoe, the agency is losing $25 million a day. He is urging Congress to make postal reform a top priority.
