Thought this was a pretty good deal, 99p for one of the huge tubes, not the normal 200ml. Offer on both shampoo and conditioner. Not sure if it was also on the blondes shampoo too.
This was in the Hull City Centre store, not sure if nationwide. Good deal if you can get hold of it though, ASDA are currently doing the smaller 200ml bottles for £1 according to their website.
