$0.99 for 200ml cough medicine at Pharmacy4Less at Parkmore (Keysborough, Melbourne).
They don't sell this on their website, but they have 31 locations around Australia. I don't know if this product is on sale at the other stores, though.

Cough medicine expires 01/18 so all good there.
Here's some pics of the medicine for the finer details:

It's $0.99 which is a bit deceptive because if you pay cash for 1 it will actually cost you $1.00. BUT, if you are really sneaky you can buy 3 and then you will get them for $2.97, rounded down to $2.95 - making the real price $0.983 per bottle!!! That's a true OzBargain savings right there.
