Just seen this in the Macclesfield branch of Sainsburys. It states on the shelf that they are down from £69.99 to £17.49. This may be a bit misleading as looking round the net they are around the £50 mark - still less than half the price at £17.49 though.
Here is the one on the Amazon site - http://www.amazon.co.uk/Russell-Hobbs-14560-Fryer-capacity/dp/B001FB6X22
- the one in Sainsburys were black too.
There were three on the shelf here along with some speakers and other electrical stuff rather than being with the other kitchen stuff.
I can't find it on the website - but to be honest I struggle to find anything on their website so I will flag it up as instore only unless someone has better luck than me!
I have a picture of the shelf label but I am not sure how to add it. So if anyone can give me a quick guide I will add it.
