But as a consumer and as a person who actually drives in Auckland, as a person who actually tries to find cheap petrol when I drive, often it is actually the boards that I see on petrol stations. Some of those boards are an indication. It is, actually, the way that a lot of consumers decide which petrol station they might go to. Some of them use apps—BP, for example. If you use the BP stations, they have a discount service. If you fuel $40, I think it's like 4c or 5c off, and, if you continue to use it, you can actually build up to huge amounts of discount. I think at one stage I went up to something like 60c per litre discount to fill up petrol. There's also an app called Gaspy, which also provides consumers plenty of opportunity for people to look at what gas stations are providing certain prices on any given day. I think that actually provides options for consumers to decide which petrol stations they might in fact go to at any given time.
