Instructions:London Evening Standard Logitech Advert today is offering a £25 voucher off the Logitech Harmony One Remote at Amazon UK
ie £94.99 - £25.00 = £69.99 with free SuperSaver delivery.
They did a similar offer a month ago that was popular here.
I've checked the code - HARMONY2 - does work during checkout and shows -£25.00.
Don't forget opportunities such as Nectar eStores for a minor cashback on Amazon purchased.
