An offer at the moment on Amazon at just under £45, abeit not quite as good on the Uk side. At current exchange rates just over £7 extra for Uk customers. Direct from Samsung is £79. Whilst at times need to be careful with Amazon it is via Samsung store on the site.
Whilst an American article it does link to the Uk site but not the right product. https://www.androidpolice.com/samsung-duo-wireless-charging-pad-deal/
The charging pad can be seen directly here https://www.amazon.co.uk/Samsung-Wireless Charging Pad Duo
I do not work for Samsung or make Samsung Products but provide independent advice and valuable contributions.
