Received this email re: my wife's e-rewards account. Thought it was pretty nice of them:

Thank you for your membership in e-Rewards(R). As a valued
member, we want to let you know how much we appreciate your
participation in the program.

As you may know from the e-Rewards Member Agreement, some
of the e-Rewards that you earned through December 31, 2001,
and did not redeem as of March 31, 2002, were subject to
expiration.

But because you have not yet had a chance to redeem a reward,
we invite you to take advantage of this special offer:

Simply update your e-Rewards profile, and the earnings that
were scheduled to expire on March 31, 2002, will remain
available for you to redeem until March 31, 2003. That’s
an extra year to save and spend your e-Rewards for one of
many valuable rewards.

Remember, with as few as $25 in e-Rewards, you can redeem
your earnings for your choice of:

Free rentals from BLOCKBUSTER(R)
Savings on Delta or United Airlines
Dollars off a Hertz(R) car rental
Hilton HHonors Points


Please don’t delay. Your e-Rewards will expire according
to the program rules, unless you respond to this special
offer by 11:59 p.m. on June 25, 2002.

Click the link below to update your profile and keep the
e-Rewards that are about to expire.
