The prices you quote are excessive. Perhaps you've tried only touristy places, rather than where the locals shop. Come to think of it, I have no idea where savvy bourbon buyers shop in San Diego County.
Anyway, Hi Time Wine Cellars in Costa Mesa lists Rock Hill Farms at $38.99, just to give one example. Okay, one more. What they call "Van Winkle SR 12 y/o", which I think is another way of saying "Lot B", for $36.99.
On Sale! Rare Breed for $25.99. Sometimes I wish I hadn't moved. Here it's over $30, even on sale.
Ooops! You haven't relocated lately, have you?
Oddly, for many things, I've found Binny's prices to be better than Sam's - but sometimes Sam's has the better deal, or has something Binny's just doesn't carry.
For a bottle of OGD BIB, though, smaller stores tend to have better deals than either of the megastores. Sometimes I think that the prices are set by the rolling of dice, though.
The prices that i quoted were from the only shop i found with that kind of selection. I have been meaning to get up to HitTImesWine, it is just so dang far (over an hour). one day...
