$130 is expensive for wine but Old Bastard is top shelf and usually priced much higher, seems like a deal.
Shipping is free at the moment.
2006 is a good vintage for Barossa according to http://www.langtons.com.au/tools/VintageChart.aspx
For comparison, Dan Murphy is selling the 2005 for $224.99 per bottle.
Only catch is need to buy 6 but you can always return the rest if you're not happy.
"This offers an aroma of chocolate-covered prunes stewing on the stove, along with notes of brick dust, black currant preserve, fresh espresso and powdered rust. Powerfully tannic and very heady, with layers of overripe fruit on the finish. Drinks like a Bual Madeira infused with black truffles, yet it somehow manages to maintain a sense of freshness. Amazing, but not for everyone. Drink now through 2025."
