Nah ~ They will keep prices the same .... They refurbed their store at Gamston and installed that mist making thingy on the salads there some 12 months ago. Woodstock reports back as she shops there en route to her Mother's place. It seems to be a unique selling point they are rolling out as they refurbish their stores but although they have vastly increased the range of produce the prices have remained much as they were.
Actually I think they nicked the idea from The Auchan in Calais where they have such a thing on the salads and a veritable waterfall on the fresh (some still kicking) fish counter.
