Xiaomi only sells them in their online shop and only in specific regions like China, Hong Kong, Malaysia, Singapore and I believe India. There are no retailers of Xiaomi phones and everybody buys them online at their shop.
There are some grey market importers for other countries, but even those originally have to buy them online at their shop in a country where Xiaomi sells.
