(CNN) - Buying stamps will now cost you a little more.
Prices rose to 49 cents on Sunday.
Just Saturday, stamps for first-class mail were 46 cents each.
The 3-cent hike is the largest increase in consumer postage prices in more than a decade for the financially strapped U.S. Postal Service.
If you want to avoid paying more for your stamps in the future, you could start buying forever stamps. They are always valid no matter what you paid for them - even if prices go up later.
