It's just not currently available on the general market, as it is offered by a start-up company with a very new sales concept. You have to ensure the Forum on the side of OnePlus (there is also a German forum) sign and, wherever possible, be a little active in it. Sooner or later, then you get an Invite (an invitation) and with this invitation you get the chance one of those ingenious smartphones to purchase. Approximately after a week you can think of with the delivery. There is also a camp in Germany will be sent from the via DHL.
If it takes too long to obtain an Invite, but there are within the forum among participants communities that support each other and provide them with Invites, as anyone who has ordered one of the smart phones, after a while of OnePlus 3 additional Invites to subcontracted receives.
That the actual principle and the idea behind the whole. This OnePlus that can (etc. as advertising costs) save as many costs and produce on demand, the price is for a smartphone that more than can compete with the current flagship products of Samsung, Apple, LG, HTC and Co, yet with the half the price of smart phones is unbeatable. There are already plenty of comparisons and tests on the network.
The OnePlus One offered here are overly expensive and I can put all my heart, either to wait until a good piece on the market is available or to obtain an Invite the forum and so amazingly low presented by OnePlus price to pay.
PS: Another important supplement for all who wish to order over the Invitesystem a OnePlus One.
The Invites by OnePlus, upon receipt, valid for 24 hours After that they expire.
The Invites by other users in the forum are valid for 72 hours.
