You can get a free Costco Gold Star card (value-$60 credit on your statement) if you are a Navy Federal Credit Union Member and have their Visa card.
I found the information on a post to deposit accounts.com. I checked it out with Navy via an E mail chat and yes, it is legitimate, if you are are applying for a Costco card for the first time. The information is on the Clark Howard site and the link is below.
