when i can get it (and i generally can't, hard to come by even in the KY), 15 is about 60-65, 20 is a buck to buck and a quarter, and the 23 is usually 225. if i remember correctly. mind you, this is at the kentucky tax base, at at OUR mark up, and in a place that doesn't quite get two bottles to rub together for the owner and someone else. but this is fair market price as far as i can tell. then again, fair market on ANY HTF is always hard to peg. pay no more than you feel comfortable, and happy hunting boys!
and, or course, if i can, i will. but please don't ask. dude who cuts my paycheck (and provides the purchasing power for the booze in the first place) gets dibs.
