Spotted in Vintage Cellar in Karrinyup Shopping Centre (Perth, WA) today, but possibly available in other VCs too.
$1 Cellar sale for a pack of 4x 200ml bottles, available for Ginger Beer, Dry Ginger Ale, and Aromatic Tonic Water.
Not sure when the deal finishes; I am guessing they are just clearing the stock.
they do this when near best before date - what's it on yours OP? and how many packs were left?
