[Q] Where to buy? topic

Hello guys, I'm new one in these forums and I would like to ask you guys if you know any trustworthy site where I can buy the oneplus one in the lowest cost(of course the original one). I found it on geekbuying for 340 $ (I would prefer it in €) but I don't know anything about his site or any other site of its kind :P so please if you know anything about this, reply to my question <3

Ps looking for the 16gb version or 64gb only if it's under 300€
