Talked to a friend of mine who manages a Spec's in Dallas. He said a lot of the brands hiked their prices 2-3 years ago, so people stopped buying them...$8 wines went to $12-$13 overnight. Then the distributors stopped carrying them. So, now they are pretty scarce.
The JJ's thing was fun, I remember it. And FWIW I've suggested it to the Spec's folks several times. I don't expect them to do it.
