Los Angeles, Calif. – April 6, 2000 – Spring Internet World, Booth #547 –Stamps.com™ (Nasdaq: STMP) today announced the ongoing rollout of Stamps.com’s revolutionary Internet–based professional shipping system to thousands of MBE centers throughout the U.S. The Stamps.com mailing and shipping system, that will be demonstrated this week in the Stamps.com booth (#547) at Internet World in Los Angeles, enables customers to compare multiple carrier alternatives.

“The Stamps.com service is an ideal way for us to build on our strengths: customer choice and world-class customer service,” said Jim Amos, president and CEO of Mail Boxes Etc. “Our strategy to become a true clicks-and-mortar solution to e-tailers and catalog companies is dependent on deploying world-class systems and Internet services through our franchisees,” said Amos.

With more than 100 million customer transactions per year and a network more than three times the size of its five closest competitors combined, MBE offers enhanced packing and shipping services using the most advanced Internet-based technology. The Stamps.com service also will enable MBE to offer numerous fulfilment services in the near future to its e-commerce customers.

Using a single user interface, the Stamps.com counter manifest shipping system gives MBE franchisees access to a variety of carriers, including the U.S. Postal Service, United Parcel Service, Federal Express, and Yellow Freight. The Price It™, Ship It™ and Track It™ utilities allow access to pricing and delivery terms from multiple carriers, instant preparation of certified carrier-specific labels and centralized tracking capabilities across all carriers. MBE franchisees can save time and money, improve productivity and expand relationships and communication with their customers.

“The Stamps.com counter manifest system connects MBE to its customers like never before, allowing them to improve service by increasing efficiencies,” said John Payne, chairman and CEO at Stamps.com. “Other large corporations in industries such as hospitality, financial services, and hi-tech will benefit from the Stamps.com mailing and shipping service to manage and control mailing and shipping costs from the corporate desktop.”

The Stamps.com mailing and shipping service is commercially available today. The mailing and shipping services run on remotely hosted Stamps.com servers and the customer pays a small transaction fee for packages and letters mailed or shipped through the system.
