First post on the site, have been lurking for months.
I haven't really found a "stash" of discontinued bourbon but I have found:
1.) Some Old Fitzgerald 1849, which I understand is being discontinued
2.) Eagle Rare 10 that has the "Single Barrel - 10 Years" band on the neck, unlike the newest bottling which just has silver stars
3.) A sample bottle of Elijah Craig 18 year which is about 2/3 full, hidden in the sampling area. I try a sample every time I'm there. The employee laughed at my offer to take it off their hands.
I would love to stumble onto a treasure trove of truly discontinued stuff though...
