注意这句: “you must make a single purchase at any participating location between 12/8 /11 and 1/31/12” 不知道是不是只能刷一次。 详细的term里面又说: B. Offer Redemption To redeem the Offer, you must comply with all of the Offer Terms, including, without limitation, completing one or more transactions (as applicable) which satisfy the requirements specified in the Offer Terms and this Agreement (the "Eligible Transaction(s)"). Your Eligible Transaction(s) must be charged in full to the Registered Card. Transactions made using the " expresspay" capability are not considered Eligible Transactions. The Offer is only valid during the times and on the conditions specified in the Offer Terms. 似乎多次也可以……
