Repeat of similar past deals where new members to nakedwines get a $100 voucher on signup to be applied against a purchase of 12 or more bottles of wine.
Cheapest dozen is their mixed dozen, mixed reds, or mixed whites I believe. These work out to be $60 plus $5 deliver (Melbourne/Sydney metro - not sure about other states)
I've purchased several times in the past and found it good value. All wines are from independent/non-big-label makers, but really not bad for a daily drop.
Make sure you opt out of the subscription 'Angels' model if they sign you up to it.
If you want to redeem the voucher multiple times, you'll need different name/phone number combinations AND a different credit card.
Once per month, Nakedwines transfers $40 from your credit card (that you must provide to register/order) onto your account with Nakedwines without asking. You only get your money back by calling them or by ordering wine from them.
