No the munks are not selling it on Ebay. Folks who paid $89 in the US are gray market selling it - it is against Ebay policy so Ebay is closing the auctions. Then most of them pop back up an hour later.... LOL
As for the munks this one time release appears to be against what they preach. It's like a publicity stunt in my opinion. They could have paid for their roof by increasing production at their Belgium doorstep... Again this is my opinion of the situation.
Although I still am curious what this stuff tastes like. I'll try the St. Bernardus ABT 12 as it is readily available and very close from what I've read.
