Through December 31st, you can receive a $10 Costco Cash Card just by paying your wireless bill with an American Express Card. This is easy money for those of you that picked up the Starwood Preferred Guest or Citi AAdvantage Amex.
First, register your American Express card here, then login to your wireless account and enroll in automatic bill pay using this card.
It will take 8-10 weeks after your first wireless payment with your registered American Express Card to receive the $10 Costco Cash Card.
The participating wireless providers are AT&T, T-Mobile, Verizon Wireless, and Alaska Digitel.
