I visited Sainsbury's in Bracknell yesterday and the vast majority of their Wella Shockwaves and VO5 hair products were priced as 'sale' items, with 75% off. These were not in-store reductions.
I bought the VO5 Extreme Style 'surfStyle' texturing sea salt spray for £0.83 (normally around £3.30), Wella Shockwaves ultra strong power hold gel-spray for £0.65 (normally £2.60) and the Wella Shockwaves styling steel gel for £0.63 (normally around £2.50).
There were 15-20 different products that had been marked down by 75% and all were found in the hair styling department. Of course, one or two products had sold out, but there was still plenty of availability on just about everything else.
These offers are not available online.
