Register your American Express Card, and you'll receive a $25 statement credit when you spend $100 or more in a single transaction on your registered Card, either online or in store with Toys "R" Us (or Baby'R'US).
This offer is only available to the first 2000 Cardmembers to register and shop before 31st August 2012.
P.S. For those who plan to register and use supplementary cards I found this condition: "Your Eligible Transaction(s) must be charged in full to the Registered Card. Transactions made on another Card account or transactions made on a supplementary Card with different Card account number are not considered Eligible Transactions."
Nothing that I need to buy, so going to buy $100 worth of gift cards and give them to the children for Christmas so that they can buy what they like.
