In case you missed the announcement earlier this month, USPS postage stamps will be more expensive in 2023.
USPS has announced that the price of a Forever stamp will increase from 60 cents to 63 cents starting January 22nd. Overall, it's a 4.2% increase across the board, with similar increases for metered mail, postcards, and international mail.
Keep in mind that a Forever stamp will always be valid no matter what you paid for it originally - so I’d recommend stocking up before the price hike!
