For those advisers unhappy with the web muscling in on their territory, at least you may be consoled that price comparison has come to virtually every sector. You probably even use services like PriceSpy, but perhaps because that was about technology it seemed 'right'. But if there is a sector that isn't subject to this kind of price comparison, I don't know what it is. You can now find out who has the best price for petrol in town by downloading the Gaspy app. It pools data of all its users and creates an easy-to-read list of all gas stations from cheapest to most expensive nearby. This free app by Aaron Schiff uses data from Statistics NZ to compare food prices in New Zealand.
