STAMPS.COM UPGRADES AFFILIATE PROGRAM TO OFFER “THE GREATEST REWARDS ON THE NET”

Affiliates Members Receive Up to 1,000 Percent Commission Increase For Bringing New Customers to Stamps.com

SANTA MONICA, Calif. – May 8, 2000 – Stamps.com™ (Nasdaq: STMP), the leading provider of Internet mailing and shipping services, today announced enhanced changes to its affiliate program, which will reward members with $250 for the first 10 new Internet Postage™ customers and $50 per customer thereafter each month of the promotion.

“Stamps.com offers the greatest rewards on the Net at $50 per customer,” said Joel Comm, owner of DealofDay.com, designed to offer consumers the best bargain hunting on the Web. “As a member of the affiliate program since the beginning, DealofDay.com has signed up more than 900 customers with the Stamps.com Internet Postage service. Not only can we pass on great cost savings for the Stamps.com service through the affiliation, but Stamps.com provides us with an important revenue stream.” Comm is also a small business customer of the Stamps.com Internet Postage service.

Breaking away from traditional affiliate program models, Stamps.com will offer, for a limited time, up to a 1,000 percent increase in commission for every new customer generated as a referral from an affiliate. During a given month, affiliates will now earn $25 for the first 10 customers referred and $50 per customer thereafter. The previous structure offered a minimum of $5 per new customer. Additionally, affiliate members will receive payment for the referrals at the end of each month, as opposed to every quarter with typical programs.

“Stamps.com has created one of the most aggressive affiliate programs on the Web by passing on such incredible incentives to our members who refer new customers,” said John Payne, chairman and CEO, Stamps.com. “The program is a cost effective customer acquisition tool for Stamps.com and an effortless way for affiliate members to generate increased revenue. At the same time, we provide the most convenient and affordable Internet Postage service to their customers. It’s a win-win situation for us and our affiliates.”

Improving on the existing Web-based program, Stamps.com now offers a feature for new affiliates that don’t have a Web presence but do have extensive e-mail and “chat room” relationships. Beginning later this month, the program will offer an easier way to link to the Stamps.com Internet Postage service through e-mail. An affiliate would simply send an e-mail to prospective Stamps.com customers with whom they have a relationship, who could then link from that e-mail directly to the Stamps.com Web site. The link would contain a unique identification number, giving the referral credit to the affiliate.
