revenuecollector makes a good point ... there is a BIG difference between "Stamps To Go" and "Stamps2Go". "Stamps2Go" operates an on-line marketplace (
http://Stamps2Go.com) for buying/selling collectible stamps. "Stamps To Go" is the USPS program (managed by the American Banknote Company) responsible for retail sale of postage stamps in banks, ATMs, grocery stores, etc.
Some years ago, when the USPS was just launching their "Stamps To Go" program, they threatened legal action against Stamps2Go seeking a cease and desist order to keep Stamps2Go from using the "Stamps2Go" name - even though Stamps2Go had already been in business for many years, and owned a United States copyright for the name "Stamps2Go".
Stamps2Go prevailed in that action - pointing out that the name "Stamps2Go" was distinct from "Stamps To Go", and that our business models, merchandise, and target audiences were vastly different. As part of that settlement, Stamps2Go did agree to post a disclaimer on our home page stating that Stamps2Go is not affiliated with the USPS.
