Simply use your Gem Visa when filling up your car this month and be rewarded.
Here's how it works
Make 2 or more transactions at your local service station and we’ll credit your account with $20*. It’s that easy.
*Open to Australian residents 18 and over. Does not include cash transactions, extended interest free or other promotional purchases. Customers who make 2 or more transactions using Gem Visa between 5 June 2014 and 30 June 2014 will have a $20 credit applied to their account on their next statement. The account must be open and not in default of your credit contract when the $20 credit is applied. A customer can only qualify once for this offer.
too easy :)
