I've been enjoying the Duval-Leroy NV lately. My local Cost Plus store has had it at 50% off, which works out to be about $21 per bottle. The bottle is decorated with Leroy Neiman gold-embossed Parisien scenes.
This thread has reminded me to go stock up on some more before the clearance sale goes away for good. I better hurry before some Flyertalkers grab the remaining supply.
