HK Airport Note5 Purchase?

I have a bit of an odd question. I need to pickup a Samsung SM9208 next week and am in HK for a 2.5 hour layover.... Not enough time to head into the city. However, does anyone know if one of the stores at the airport carry the 64 GB Model? I know that there are a few cellphone shops in the airport but was wondering if the 64 GB model was readily available in HK. Unfortunately, eBay isn't an option where I'm living and traveling too so window is likely all I can get to pick this up.

Thanks for all the help!
