Costco $10 Bonus For Auto-Paying Wireless Bill with American Express

Costco and American Express have a promotion where you can earn a $10 Costco Cash Card when you enroll on their page and then sign up to pay your wireless phone bill automatically with any American Express card. All wireless providers distributed by Costco are eligible: AT&T, T-Mobile, Verizon Wireless, Sprint and Alaska Digitel.

To receive a $10 Costco Cash Card, enroll any eligible American Express Card by filling out the information below. Then, sign up to pay your eligible wireless bill automatically on the same American Express Card – it’s as simple as that. Automatic bill payment is a convenient solution that helps ensure that your bills get paid on time every time. Plus, you can earn rewards if your Card is enrolled in a rewards program. Offer good from now until March 31, 2012.

I remember seeing this promotion in the past before, but you had to use the Costco AmEx card, whereas this promotion works for all AmEx cards.
