I really wish the Commerce Commision would do something about AA smartfuel, it's causing serious skewing of the petrol market while the AA sit there and blame fuel companies for profiteering.
The retail margin is being skewed to cater for the heavy discounting. For many years retail margins were pretty constant at sub 20c, they're now well over 30c. This margin allows heavy discounting to occur while artificially inflating the price for those who don't have discount vouchers or smartfuel card.
The exact same situation existed in Australia and resulted in the ACCC banning fuel discounts in excess of 4 cpl because heavy discounting was skewing the retail market creating an unfair marketplace.
A pity there is no real investigative journalism on TV these days. This the sort of thing Campbell Live would pick up on if it was still on. So industries can now do it without being challenged.
