If you spend $5 or more you will get a $5 credit. Each registered American Express card is eligible for 3 credits. Registration starts August 1st 2014 and the spending must take place during August.
Online purchases will not qualify.
Every American Express card with a unique account number will count as a separate card for this promotion, including authorized users on American Express branded cards. American Express cards that are branded by other companies (like Citibank and Fidelity) will only receive one credit per account. Serve cards are eligible, but all other prepaid cards are not eligible.

American Express randomly runs great promotions so I like to have as many American Express cards that have no annual fee as possible.
Hopefully, as the date gets closer, we can figure out a store to call that will process a useful credit.
