Want to make a quick profit?

First class postage is going up again, one extra penny May 12th for a total of 42¢.  If you buy some Forever stamps before that date, you'll be able to buy them at the 41¢ rate and they'll still be valid for First class.  That's a profit of 1 penny for each stamp you buy, or 2.4%  That's better than most banks.

Of course, it's not really much of a profit unless you use a lot of stamps, since there's really no way to convert stamps back into cash, but if you do, you've got 3 months to stock up!
