Looking for a nice deal on a new computer? Today, Amex rolled out another new offer for cardmembers–when you register your American Express card for this promotion, you’ll earn a one-time $100 statement credit after spending at least $599 at Dell.com.

This offer is good both online and via phone (1-800-999-3355) through July 21, 2014. Paypal transactions, E-Gift Cards sent directly to the recipient’s email address and authorized resellers of Dell products are excluded. Enrollment is limited.

Update 4/23/14: This offer is no longer available, as the enrollment limit has been reached. As of 4/23/14, see this post for a current list of Amex Offers.

As usual, cardmembers can enroll in one of several ways:

• Log into your americanexpress.com account and click on the “Amex Offers For You” tab. Click the “Save Offer” button next to a deal to enroll your card.
• Use the American Express iPhone App and visit the ‘Offers For You’ tab in the ‘Membership’ section
• Through Facebook at amex.co/facebook
• On Twitter by connecting your card, then tweeting #AmexDell.
