Popped into local Morrisons yesterday and saw that they were doing half price on all the varieties of Head and Shoulders Shampoos and Conditioners - Original Price: £3.69, sale price: £1.84.
The Pantene shampoos and conditions were also half price - Original Price: £2.85 reduced to £1.42.
I was very happy and supprised as I don't think I have ever purchased H&S at half price. Obviously, I stocked up :)
I think the expiry date was 4th May, but I'm not 100% sure on this.
I hope this is deal is helpful to some.
