Sadly, I didn't buy any "forever" stamps. I had 26 41-cent stamps left over from my roll of 100, so I had to swing by the Post Office yesterday for the 1-centers before mailing off the bills I did on Sunday. Not smart smart planning, and not exactly thinking of the future:
Do the math: In 1970, a first-class stamp cost only 6 cents. Since then, there have been 17 rate changes, amounting to a whopping 700 percent price increase.
