2004 Coonawarra Cab/Shiraz for $4.74 ($56.88/dozen)
Then pay $71.88-$10=$61.88=$5.16 per bottle for the first case of a Coonawarra Cab/Shiraz with some age to it (2004). Delivery is $5 per case.
Use the $15 voucher noted below then it's $71.88-$15=$56.88=$4.74 per bottle plus $5 delivery.
In addition, you may also get some buckscoop $ back!
Even if (like me) you have bought from them before so have already used your voucher, this seems like a good deal. I haven't tasted the wine myself, but it is from a winemaker with some experience behind him (http://www.lawrencevictorestate.com.au/winemakers/pat_tocaciu.htm) so at least it should be a good barbecue drop (as noted on their web site here http://www.patricktwines.com/toccas.php), and with some luck it could actually be really good....
