USPS 421 Retail Clerk Practice Exam

Forever stamps are a unique type of postage offered by the United States Postal Service (USPS) that allows customers to send a standard letter, regardless of future price increases in postage. When you purchase a Forever stamp, you pay the current rate for first-class mail, but you can use it indefinitely, even if the price for mailing a letter rises in the future. This feature makes them a convenient option for customers, as they eliminate the need to buy multiple stamps if rates change.

The ability to use these stamps without worrying about future price adjustments is particularly appealing, allowing individuals and businesses to stock up on stamps without concern that they will become obsolete or require additional payment in the future.
