Was hunting down the 1200 Netgear Power line double packs for 21£ in Saintsbury's posted here http://www.hotukdeals.com/deals/netgear-ac1200-powerline-with-passthrough-socket-21-sainsbury-s-instore-fullham-2488548
. Found them in Cheltenham, Tewkesbury Road but had a scan of this ac750 for 15£. Also found a tp-link WiFi multi function extender for 3£ which I will post separately.
Found the price tag in Gloucester but shelf was empty and they looked on their system and told me there was stock in Cheltenham. Thus obviously national price reduction. 1 1200 netgear power line adapter kit for 21£ and one netgear 750ac adapter left on shelf in Cheltenham, good luck everyone.
Interestingly the prices were not updated on the shelf and it might be worth scanning other netgear end of line stuff that they are obviously getting rid off.
