Goundrey Reserve Mt Barker Riesling 2008 - $13.95 (another constellation wine) from Winemakers Choic
If your buying it might be worth double checking that $13.95 is the best price you can get on it. From what I can find its good, with the original price being $25 or so and the nearest online competitor I can find is selling at $16 a bottle.
Delivery cost from winemakers choice is in the range of $8 to $20 depending on where you are and they charge a 2.5% of the value of the wine in 'insurance', which I guess is fair enough. At least you can claim if the wine dies on route.
