I got this code after completing their 2018 survey, given the generic nature of the code I'm quite sure it's not targetted.
No end date given.
A quick browse suggests this one might be great value at $54.99 after discount + shipping ($9.99 per case in NSW/ACT $14.99 per case for other States): https://www.beercartel.com.au/mixed-boutique-beer-12-pack/
If you have any problems you might need to complete their 30 second survey at https://www.surveymonkey.com/r/AusCraftBeerSurvey
Even with the $10 off, I'm struggling to find anything worthwhile. Really doesn't help that the website only displays single beer prices without an easy option to search for cartons or 4/6 packs.
Recent deals from Booze Bud and Craft Cartel are much better.
