sbiddle - do I know why the Commerce Commission took the action they did? Well, ostensibly any action the Commerce Commission takes is meant to be in the interests of helping consumers. In this instance, it was because they believed that Visa and Mastercard were involved in price fixing. Well, we all know they were. I should probably point out that there is price fixing in other industries too. Petrol for one. Electricity for another. I don't see the comcom looking into those.
But anyway, my point is that this action by the commerce commission has directly harmed consumers. With advocates like that, who needs enemies? They should have clamped down the instant any merchant charged a credit card surcharge without lowering their prices for non-credit customers. Why? Because that merchant is not passing along costs because the costs are factored into their non-credit purchase prices already. The credit card surcharge is pure profit to them.
