$35 price - seems very cheap, also better than a crappy plastic one, which will leak and stink up the car!
Was $65 - But timely reminder when the plastic ones pop up.

Obviously not as cheap as the $20 one from a while back, but this one is actually suitable for petrol (that is what it says anyway) and Pro-Quip is a brand name.
Note: what makes it suitable for petrol, a special valve or child lock?
Maribyrnong and Melb. City have stock in my area.
Otherwise $10 delivery is what came up for me.
