How or where can I get an unlocked white s7 edge if I live in the United States?

[AC Question]

I live in the United States and I really want a white s7 edge but they don't sell that color here. I tried looking for SM-G935U unlocked s7 edge phones but I haven't seen any in the color white. Can I buy one from the UK samsung store then give it to best buy or something so they can unlock it?
