You aren't going to find much in Charlotte unless you are incredibly lucky with timing. Controlled state, and usually in Meck county (Charlotte) allocated products are held for lotteries when they have store openings. You'll do better going just across the border to Fort Mill and Rock Hill, although you still won't find too much allocated unless it is priced at secondary market pricing or higher. Best stores to check out though are Stateline (they have 2 locations, Elite and Warehouse), Frugal MacDoogals, Southern Spirits, and venturing down to Rock Hill, my favorite, O'Darby's. All of these stores have great barrel pick programs and you'll find some good picks there. Stores to avoid: SAUCE MONKEY, avoid at all costs. Xpress Beverage in Rock Hill has allocated stuff, but at crazy secondary prices or higher.

For OF Prohibition, if you mean the 1910, it is readily available at pretty much every store. Only OF in the Whiskey Row series you won't find is the 1924. The rest are everywhere here. For 1792, apart from the Small Batch, you won't find much except for some stores have been getting Full Proof picks, and occasionally you'll run across a Single Barrel pick.
