You nailed it with 'extremely low inventory wines'. Even though people complain about both, I find the lottery situation at least more fair. The first come first serve basis is heavily biased against anyone who cannot schedule their week and day around the 8:30 AM Thursday release. Since most of the popular 'low volume' wines seem to be gone by 8:32.
At least with the lottery system it seemed to place people on a somewhat even footing. There is no perfect way to allocate wine that is in such high demand and low quantity.
Like OTW, I'm now less inclined to participate in the Classics , and will not go back to standing in line at Stores on a Saturday morning. Mind you, I gave up standing at stores waiting for the allocation in about 1999. I actually only did that once, and was cured of any desire of repeating the exercise.
