Startup Idea : Cheap Fuel Prices

Fuel prices are always changing and its difficult to know which local fuel station is offering the cheapest prices. In Australia, consumers either drive past a fuel station to find out prices per a litre or they purchase groceries from woolworths and coles to obtain a discounted fuel ticket. We need to beat the supermakets and give the power back to the public. People shouldnt need to purchase groceries to get cheaper fuel and petrol stations should advertise current fuel prices. Those wanting to fill up should be able to choose which station they want to puchase from behorehand, based on travel distance and fuel price. The method to purchasing fuel works in two ways. The first method is to do some grocery shopping and spend over $30 to get a docket that enables us to buy cheaper fuel from supermarket owned petrol stations. Secondly the driver realises the fuel tank is nearly empty and stops at the nearest petrol station and the care factor of price depends on how desperate they are for fuel.
