How can I buy (online within the US) a factory unlocked HTC One M8 with Windows OS?

[tabraoui]

I can't find it on Amazon (they only have the Android OS). I'm not in the US but someone will pick it up for me. I need to be able to buy it online and delivered to an address in Orlando.
Any help would be appreciated.
Thank you,

There is none. There are only M8 for Windows phones for Verizon, ATT, and I believe T-Mobile.

The Verizon model is technically unlocked, but MMS and some other small details may or may not work.

There are lots of unlocked M8s on eBay... I just bought mine there.
