You can purchase LV and a few other designers (D&G, Dior,Juicy) on Eluxury.com. They only ship to US.
Coach you can find on Coach.com , Nordstrom.com or Macys.com Also coach will only ship to US adresses.
I usually order most things from Nordstrom. You can however get Juicy and some other designers to ship to APO or us terriorties for some reason Coach will not ship anything outside the us online.
