Loads of shampoo and conditioners only 89p in Boots. Don't know if it's national but seen them in two different stores so it's worth a look. Not on the clearance stand but in its usual place with a price mark down in front. Many other hair lines reduced too but these seemed the best.

It's the different ranges of these: http://www.boots.com/en/TRESemme-Vitamin-E-Aloe-Colour-Revitalise-Shampoo-500ml_14752/
