The price of petrol I paid during February 2017 averaged $1.20 per litre for 91 Octane unleaded add 10-15 cents for 95 Octane and usually 15-25 cents for 98 Octane. Petrol prices are the consistently the lowest they’ve been since the start of the year.
Note that fuel prices vary according to area and the level of competition and a whole heap of other factors like shopping discounts and so forth, however unreasonable high prices (relative to crude oil prices) is greed. Also note that the Octane I post here represents Australian measurement which is different from those in other countries eg. US.
