Back on again. As happens most of the time, no Terms & Conditions are available online, so the expiry date is unknown. (Rang Customer Support and they couldn't access the T&C. Promised to pass on the suggestion to make the T&C available online.) Hopefully they're the same as the ones that were available for this previous deal, so the promo should last a week.
There's lots of $10 and $20 wines that you can buy to maximise the deal.
There's also Tinnies IPA/Pale Ale 6pk cans available for $20. (Haven't tried them yet. Might be a good excuse to do so now.)
