I've been sending out letters at work. I used up a bunch of those forever stamps. (Yeah, forever turns out to be just about 3 months.) So I've got to use some of the old 41 cent stamps and add a penny stamp.
I thought about using 42 of the 1 cent stamps to pay the postage on one envelope, but I only found there is only enough space to put 40 of the suckers on. And the mailing address would have to be in size 4 font. Better not get Newman upset. I like getting my mail.
