Thank you so much for everyone's input. I bought 3 bottles locally already. I need to buy about 10 bottles. I was hopping to save some money by buying at the airport. My dad bought 2 bottles of Courvoisier XO in TPE for $69.99 each back in 2011, which was about $30 cheaper than our local prices at the time. I guess things have changed. We want to bring these to SGN. My family will fly in two groups with connections in HKG and TPE.
