I haven't seen much for Krug lately, problem is first choice or liquorland don't stock it so closes the door on deals from there, unless you'd settle for Dom. If anything Krug is going up, vintage cellers have shot the price of vintage up to $600, though with 15% off today via Cashback you could get it for $302.28.
Other options are vivino:

10% off with welcomeau10 and another 5.6% via Cashback should get you around $275 (can't remember exactly how they calculate their cashback). Includes delivery.
At this point someone like qaz might jump in with a better vivino code or alternative deal
