This thread has examples after release at $90 in some local bottle shops. I've seen them in Dan's around release time for under $100.
My suggestion was to buy a bottle to try so $90 to me seems pretty "reasonable" compared to dropping $300 plus on 6 wines that you might not like. You either want to try it or you don't.
To me $120 or so is reasonable for the quality and I'd pay that for a bottle every now and then if I wasn't on the list. People seem happy to buy things like RWT, Quintet, various Standish and Henschkes and plenty more for that price and I'd have no hesitation in holding Wendourees in that class of wine. I get that it's well above the offering price but that's only because the Brady's haven't gone all Penfolds and jacked up prices, because they could have and they'd still sell out.
Anyway, I'm not fussed if they don't join the list, more for me.
