ASB have a couple of credit card offers based on AA Smartfuel:
Bonus 95c per litre
Open a new ASB Visa Platinum Rewards credit card and get a bonus 95c off a litre of fuel once in each month for the next six months when you spend on your new ASB Visa credit card. Make sure you're an AA Smartfuel member, and then switch your rewards to AA Smartfuel. Terms and conditions apply. Redeemable at participating BP and G.A.S. stations. Offer ends 31st October.**
Bonus 50c per litre
Open a new ASB Visa Rewards credit card and get a bonus 50c off a litre of fuel once in each month for the next six months when you spend on your new ASB Visa credit card. Make sure you're an AA Smartfuel member, and then switch your rewards to AA Smartfuel. Terms and conditions apply. Redeemable at participating BP and G.A.S. stations. Offer ends 31st October.***
Since AA Smartfuel discounts don't expire until the following month, you can get $1.90 off/L every second month. Also the minimum spend is only 1c in order to get the 95c off/L for that month.
Based of Visa Platinum Card:
Cost: $40 half year annual fee (if you can cancel the card in time); 6c (1c per month)
Offer: 95c x 50 x 6 = $285 (if you fill up exactly 50L)
Overall Profit: 285-40-0.06 = $244.94
