Just saw this offer on Facebook. The code is SIXPACKS - ( my local store says the code is SNACKS, that is wrong.)
"Buy one 6 pack of beers or ciders from select liquor stores and get another for free. Valid from 13/7/2021 to 14/7/2021 11:59pm AEST or until fully redeemed. Valid only in VIC and NSW. Use code SIXPACKS at checkout."
