Stamps.com Software Automatically Updated With New Postage Rates

LOS ANGELES, CA, May 11 (MARKET WIRE) --
Stamps.com(R) (NASDAQ: STMP), the leading provider of online postage and
shipping software solutions to approximately 400,000 customers, announced
today that all Stamps.com PC Postage(R) products already include
everything customers will need to calculate and print the new USPS(R)
rates that go into effect today. Stamps.com solutions also include postage
discounts not available at Post Office(TM) locations or through
traditional meters. PC Postage customers can learn more about the postage
increase at Stamps.com's website. Stamps.com's customers can completely
avoid the Post Office -- an even greater benefit whenever the USPS raises
its rates and Post Office locations across the country become crowded as
non-PC Postage users rush to get additional postage and to figure out the
new rates.

Some of Stamps.com's PC Postage features include:

-- Automatic rate updates for free -- unlike providers of other solutions,
such as traditional postage meters, who typically charge a fee every time
a postage increase occurs.

-- Easily print 2 cent stamps with NetStamps(R), Stamps.com's feature
which allows customers to print postage that functions just like ordinary
postage stamps.

-- Savings of up to 80% over traditional postage meters by eliminating the
need for proprietary ink refills, costly reset fees and expensive,
long-term contracts.

-- Postage discounts of up to 11% on Priority Mail(R), up to 5% on Express
Mail(R), up to 8% on International shipping, and 10% on package insurance,
versus rates at the post office. Even larger discounts are available to
qualified high volume customers (contact Stamps.com to find out more).

-- Free delivery confirmation and free package pickup with Priority Mail
service.

-- Hidden Postage(R) for discrete shipping charges for eCommerce
businesses.

-- Automatic address cleansing to avoid the cost and hassle of wasted
postage.

"We are committed to delivering a seamless postage and shipping solution
to our customers, particularly during rate increases," said Stamps.com
president and CEO Ken McBride. "That is why we have worked to make this
and all upcoming rate changes as pain-free as possible for our PC Postage
customers."

Stamps.com is offering a free webinar today, May 11th at 11 a.m. PDT to
teach small business owners everything they need to know about the new
USPS rates, and about options that are available to reduce mailing and
shipping expenses.
