Spend $60 or more on the saved Card in one transaction in store at Costco North Lakes, excluding Petrol, before 30th June 2014 to receive a $10 statement credit. Limited to first 2,000 Cards to save the Offer.
Looks like this could be targeted to Amex card holders around Brisbane / North Lakes area for the newly opened Costco.
I found the offer in the offers and places section of the Amex website - not sure if there is a direct landing page for this deal.
Doesn't appear for me. And also mentions it is for the North Lakes QLD store only.
