What Is the Current Value of the USPS Forever Stamp?

In 1989 the British introduced the first stamp which was a "non-denominated" stamp, meaning a value was not printed on the face of the stamp. Instead, the stamp was sold at current prices, but could be used anytime for a particular service. The goal was to workaround the problem of rapidly-changing postal rates.
The United States Postal Service introduced the "Forever Stamp" in 2007. The concept was to introduce a stamp that would always be worth the current first-class postage rate. In April of 2007 the Forever Stamps were worth $ 0.41 each, May of 2008 saw the value and cost increase to $ 0.42, and in May of 2009 they were $ 0.44.
The Good and the Bad
This works great when you are using a Forever Stamp (abbreviated FS in this article) to mail a one-ounce, regular-sized, letter, via First Class Mail. Simply put the stamp on the envelope and you're set.
The problem is when you need to know the current value of the Forever Stamps. This is particularly important if you are using multiple forever stamps to ship a large letter or a small package. The Post Office does not provide a convenient way to know the current value of a Forever Stamp - I tend to think this is primarily because the Post Office prefers people to print postage or ship packages in a Post Office. I believe the reason for this preference is due to security: the Post Office can better track "who" is shipping "what" (which makes sense to me!).
Several Solutions for Knowing the Current Value
If you find yourself needing to know the current value of the USPS's Forever Stamp, you have a number of options.
One option is to go to the Post Office's web site: www.USPS.com. You'll need to:

• click "calculate postage" on the top menu bar
• select the option to "Calculate Domestic Postage"
• select "United States" as the destination
• enter a beginning and ending zip code (you may use your own zip code for both)
• the mailing date/time default variables should be fine
• click the letter shape option
• enter a weight of 1 ounce
• click "continue"
• select the proper shade for your letter and click continue

The next screen will have a list of mailing options, the First Class Mail Option and Rate should be listed. This will show the current value of the FS. This method is a bit cumbersome.
Another option would be to write down the current value of the Forever Stamp on a post-in note and keep it near your desk. Drawback is that your desk will appear more cluttered, and you'll have to remember to change the value whenever the value of the Forever Stamp changes.
Another option would be to save the value somewhere on your computer as a reference. Perhaps in a text file or maybe as a new Contact, titled "Forever Stamp". The drawback with such an approach is that you have to remember where you saved the value, and you also will need to update the value whenever the Post Office changes the first-class rate.
