Sorry, I cant edit my post yet and wondered if that was clear enough to leave as is.
It was supposed to read "Voucher for £1876 price if you cant wait for Banggood: XMWDANGA"
i.e. Geekbuying price is £1876 and can be ordered today with that voucher. They might match Banggood though I am waiting on a reply. Honestly I might just buy it and sell on later if I can fit the setup I want in my new house (yet to be found/purchased)
Mega - just looked on Geekbuyer and the one they have states - Native Resolution: 1920 x 1080.
Whereas Banggood states - Native Resolution: 4K (3840 x 2160)
Yea, I messaged them about that also - it is almost certainly a mistake on the Geekbuying website as the model number is the same. On ******** they are still using all the promo images from the non-4k version - these sites make mistakes on their listing pages regularly.
It's worth emailing and confirming everything so you have recourse.
