NetStamps® are a Stamps.com product feature that enables Stamps.com users to print sheets of NetStamps for use like regular postage stamps. Earlier versions of Internet postage required that postage be printed at the time of mailing
Now you can use Net Stamps like regular stamps; printing and storing them for future use without worry of expiration. Net Stamps are printed on specialized stock that allows for printing variable prices and can be used to pay for all classes of mail and most widely used Extra Services.
