I went into my local Robert Dyas today and they were doing 20% of kettles and toasters - even already reduced ones.
They had a white Breville Illuminator for £14.79 reduced from £30 with then a further 20% off this price.
Another good deal I noticed was a Kenwood Neon Kettle and Toaster pack which was apparantly £59 but had a £50 sticker on it. It was then reduced to £27.99 I think.
Pretty sure it was like this one http://www.amazon.co.uk/Kenwood-Kettle-Toaster-Multipack-MP352/dp/B000VWP052
Not sure if the 20% was off these packs as well, the sales assistant said she thought so, and pretty sure you could push for it as it says 20% off any kettles/toasters on promo material.
I hope this wasnt just specific to my store.
