My family will be connecting in HKG and TPE. I need to buy a few 750 ml bottles of VSOP and XO cognac (preferably Courvoisier, but Remy Martin or Henessy are okay too). I just wonder if it will be cheaper to buy them at the duty free section in HKG and TPE. I live in California and my local Costco has XO Courvoisier for $129.99 and Remy Martin VSOP for $33.99. My local BevMo has similar prices to Costco. Any input is appreciated.
