Noticed today in my local Tesco (Pitsea) they had the Withings Smart Body Analyzer at half price, good saving if you are in the market for a set! Seem to be pretty much full price everywhere else. Unsure if national as obviously on a yellow ticket. But if your store stocked them originally then you might be in luck.
