Got this in my email awhile ago as it's a deal for Farmers Finance cardholders though its open to anyone via the above link & you can pay by credit card.
Offer is for a 14-bottle case of either white, red or mixed wines - $99 for the standard bottles & $149 for the premium bottles.
Pricing includes GST but not delivery - delivery to my place in Auckland was $7.99.
The conditions say limit of one 14-bottle case per customer though it seems you can add multiple cases to the shopping cart.
The conditions also say it can't be used with any vouchers though I was able to use the 20% voucher code 'TWENTYOFF' (valid until midday Monday 5th of October 2015). This meant I was able to buy a premium case of red wines for $127.19 including GST & delivery ($9.09 per bottle).
The voucher code also seems to work with the standard cases meaning you could pay $85.60 including GST & delivery for 14 standard bottles ($6.14 per bottle).
Note that I've placed an order & received a confirmation though I've yet to receive the wine delivery - it's possible that they could retract the 20% discount before my order is sent though it's still a good deal even without the extra discount.
The Wine Society have a 100% guarantee that if you don’t like a wine for any reason whatsoever, they'll credit your account. All you need to do is call or send them an email and they’ll arrange the credit. Note that I haven't taken advantage of this guarantee before so I can't vouch for it's credibility.
