FREE BEER with purchase of newspaper! Stubby of Carlton Natural to be exact, from Bottlemart. WA Only?

Page 78 of today's West Australian has a large ad for a free stubby of Carlton natural with presentation of the ad at Bottlemart, Bottlemart Express or Western Cellars. OK so you have to buy a copy of the West but lots of people will anyway. Sorry I don't have a camera to take a photo of the ad and there doesn't seem to be anything on Bottlemart's website. Not sure if it's WA only, anyone?
