LOS ANGELES, September 13, 2004 -- Stamps.comŽ (Nasdaq: STMP) today announced that it will focus on the top categories of its popular PhotoStamps product. The top two categories-babies and children, and pets and animals-will continue to be accepted on the PhotoStamps website. The PhotoStamps website will also continue to accept other popular categories of images including landscapes, nature, wildlife, business logos, and charity logos. Images that include adults or teens will no longer be accepted via the PhotoStamps website, but will continue to be accepted through trusted channels such as approved photographers or portrait studios.

The public response to PhotoStamps has been very enthusiastic. More than a million individual PhotoStamps have been ordered since the service was launched on August 10th, and more than ninety percent of customers surveyed said they will order PhotoStamps again. Currently in a market test, PhotoStamps continues to respond to consumer demand while refining its processes. The market test of PhotoStamps is expected to continue through September 30, 2004.

"We are overwhelmed by the early success of PhotoStamps," said Stamps.com CEO Ken McBride. "Consumers have told us that PhotoStamps allow people to share memories -- from new parents sharing baby pictures to adoring pet owners sharing favorite images of their animals. We want to focus on what has been most successful to date and make appropriate changes to the product during our test phase."

McBride added, "We have limited the use of the product in certain categories in response to the abusive actions of a few people that went to great lengths to use the product in inappropriate ways. We want to preserve the essence of the product that tens of thousand of customers use in a fun, creative, and positive manner."

Business and charity applications of PhotoStamps have already proven to be very popular, with more than a hundred inquires to date regarding higher volume uses of PhotoStamps. Stamps.com plans to increase its efforts to expand higher volume business and charitable applications of PhotoStamps, while also continuing to enhance the availability of PhotoStamps to consumers.
