Sole Mio Extra Virgin Olive Oil - 5 litres for $10
Expiry is in 2014. They had at least 12 bottles of the stuff on the shelf. It was on special a month ago $20 (50% off) so it must usually be $40.
Spotted this today at Coles - West End Plaza (Spencer Street Mebourne next to Southern Cross station).
Can't upload photo at work - see what I can do tonight.

Good price though $40 is a rather inflated price particularly given that this is not a normal line Coles run and has never been sold for that price.
