USPS Approves Stamps.com's NetStamps
NetStamps will require special paper, however, which the existing service does not. The new Stamps.com Version 2.5 software, which lets users print both NetStamps and Internet Postage interchangeably, is available for immediate download at www.stamps.com.
Stamps.com's NetStamps customers will pay a monthly membership fee of $15.99 for unlimited use or $4.49 plus 10 percent of the cost of the printed postage. Those prices are in addition to the postage itself.
