nothing is cheap comparing to canada, everything is more expensive, except for "gas", and some services such as dry cleaning, ironing, clothes alterations, house cleaning.. but these services are sucks here anyway :):)..
btw, here isn't GAS.. here is PETROL.. don't ask, where is a GAS station, they won't understand you.. :) and in the supermarket don't ask where to get a cart, they won't understand you.. ask for "trolley" :)
