Beat the first-class mail cost increase
Are you penny-wise? If so, this is a perfect time to save some Lincolns. On May 12th, the US Post Office is raising the price of the first-class stamp by one cent, from $0.41 to $0.42. I can only conclude they make a killing on one-cent stamps.
Luckily, I've been buying Forever Stamps, which sell for the same price as the current first-class stamps, but remain valid for first-class postage no matter how much it increases. Given the stock market results over the last few quarters, my stamps have out-yielded my index stocks by a considerable margin.
I'm mystified by people that still buy priced stamps. The post office apparently sells a lot of $0.41 stamps, though, and will probably sell as many $0.42 ones to those who value the appearance of the stamp enough to offset the annoyance of keeping a stock of one-centers. Me, I'm buying Forever Stamps, and doing it before May 12th.
