Just ordered the 2013 Piper-Heidsieck Rare Brut Millesime Champagne for $210. Less the $50 discount, with free shipping, plus tax and their annoying $3.95 fee, the total charged was $175.43. I should also get $30 of that credited back on my Marriott Bonvoy Amex.
All-in ~$145 for the 2013 Rare, I feel like that’s something that @MChang would be proud of.
For those trying to stack the $50 new member credit as well, this bottle may work as it gets you above the $150 after the first credit. Not 100% sure though.
