I have to agree with Martin. I happen to know these have been on the market for several years, and with significant magazine and trade marketing effort. The price has actually decreased since the introduction of the Stamp into the marketplace. Perhaps you will then have some idea as to why many of us get our drawers in a bunch when some dipwad has the audacity to do as you have done here.
Theft is theft, sir, no matter if it is a postage stamp, a million dollars, or just an idea.
