Mod Update 2 — Discussion continues here.
Mod Update 1 - WARNING
There is no deal here, now
Four sisters wine is not honouring what was previously stated.
Liking their page + registering your details only gets you a reminder to go back to their site again and see if you are one of the first (unspecified) people to get there (as vouchers are limited)
It also gets your agreement to have their app on Facebook and among other things, let them impersonate you on you Facebook wall.
This post is being kept to update those who Liked under the previous offer and in case either Four Sisters Wine or the promotions company who were involved, make moves to honour what they promised.
Following is what the OP (actually a Rep) posted on OzBargain
Message on the Four Sisters Wine page:
http://www.facebook.com/foursisterswine
We're offering our Facebook friends the chance to sample our new family fabourite.
Simply like our page, print your coupon and redeem your free bottle at participating Dan Muyrphy's stores - it's that simple.
Hurry - we only have a limited number of samples to give away.
Mod: Added rep tag as OP is affiliated with the company (app maker).
So wait, you found this on Facebook today or your offering it on Facebook today?
Because one implies that you have nothing to do with the company offering the deal and the other implies that you are from the company offering the deal.
Also, Four Sister Swine. Heh.
