These Stamps Are Forever, but the Savings Are Not

I used to proudly proclaim I was a bargain shopper. I would get goose bumps when I saw a store sign that said, "Save Now."

But the truth about money is that when you spend, you never save. Yes, if you buy one pair of shoes for full price and get a second pair for half off, you may have gotten a bargain. However, you have not saved a penny. You have just spent less.

I'm reminded of that as I contemplate whether I should stock up on the Postal Service's new Forever stamps. They were introduced to help ease consumers' aggravation at having to pony up additional postage because of an increase in the price of a first-class stamp. The stamps are called "forever" because they're good for any future single-piece, first-class envelope weighing one ounce or less, no matter how prices change in the future.

The Forever stamp's launch comes as the cost of mailing a first-class letter is about to rise to 41 cents, from 39 cents, effective May 14. But you don't have to wait until then to purchase the Forever stamp. It is available now for 41 cents, although you might want to wait to use them until May 14 or thereafter. The stamp depicts the Liberty Bell with "forever" printed on it. And there is no limit to how many you can buy. So far the Postal Service has sold more than 500 million. In anticipation of demand, the service has printed 5 billion, according to Mark Saunders, a Postal Service spokesman.

So should you rush out and stockpile these stamps?

I wouldn't. And I wouldn't for the same reason I'm financially cautious about filling my pantry with food and household items I might not use for months.

Before you buy in bulk, consider the cost of having that money tied up in items you won't use for quite some time. It's like the frequent sales at the grocery store. If you see a sale of 10 bottles of apple juice for $10, is it always a good deal to buy all 10?

The answer: It depends. If you have three kids like I do, you may go through those 10 bottles in a week or two. And because the juice might not be on sale for another three weeks, it could be a good buy. However, if it will take weeks or even months before you use that juice or some other item, then you should keep the money in the bank and earn interest on it. Or put that money toward the purchase of something you really need.

In the case of the Forever stamp, the same strategy should apply. The stamp would be a good bulk buy if you know you'll have a lot of mail to send after future rate increase is announced. Just make sure you buy before that increase takes effect, because the cost of the Forever stamp will rise to the new price for one-ounce, single-piece first-class mail.

The good news is there's no need to fear massive hikes in the cost of mailing a letter. Last December, President Bush signed the Postal Accountability and Enhancement Act, the first major change to the Postal Service since 1971. The law requires that postal rate increases be tied to the rate of inflation, as measured by the government's Consumer Price Index.

Since 1983, the last year that the Postal Service received a federal subsidy, the price of a first-class stamp has remained at or near the rate of inflation, Saunders said. Under the new law, the Postal Service has the option of applying for one more rate increase by Dec. 20 -- after that date the inflation linkage takes effect.

Though you may not want to hoard Forever stamps just yet, there are some postal pricing changes that are clearly a good deal. The Postal Service is switching some of its pricing to reflect differences in envelope and package size.
