what about the price of a stamp...it will go from 39 cents to 40 cents, then it will jump to 45 cents and 50 cents. no penny jumps
A single stamp could go from 39 to 40 cents, but unless they're going for a money grab, you could still get a book of 10 for $3.90 or 20 for $7.80
If they made a stamp, just a plain old first class mail stamp, that they promised would be good forever for a standard (<1OZ) mailing, I'd buy a thousand of them tomorrow.
Wouldn't have to....Just sell them in lot's of ten....
