OK way I got this is I purchased the cheapest accessories from Samsung which is a adaptor for 7 quid, then get offered a 10 percent off code to use on my next purchase. So buy the adaptor first then get the code, (have to share link via Facebook or twitter FYI). samsung.com/uk/…uy/
Then add the tablet above to basket and the controller is added automatically.
I personally had a old Samsung tablet so traded that in for £100 to make it 557.10 total.
Plus 4 percent from Quidco
Ps - tip below return the adaptor for free for another 7 quid back
