A new Postal Service video explains the price changes that took effect Jan. 22.
The changes include a 2-cent increase in the price of a First-Class Mail Forever stamp, as well as a 3.9 percent price increase in Priority Mail and an average increase of 3.3 percent in retail prices.
USPS released the 3-minute, 40-second video this week.
