Joined a new program on the weekend that looks quite interesting....Aussie Fuel Cards.
Basically its a reverse? auction where you make bids on Caltex fuel cards with the aim of being the highest 'unique bid' and whatever that figure is, you end up purchasing the fuel card for that price.
They claim that you can buy fuel cards for 95% below their face value. Might pay to read the strategy guide on their web site before you get to far into it....
Let me know how you go with it......Aussie Fuel Cards
