Not familiar with face creams but..... Picked this up today in store at Superdrug, Arnold, Nottingham.... L'Oreal Skin Perfection correcting day moisturiser 50ml shelf price was £3:50 (which looked cheap next to others in the range) The price at the till was only £1.40.!.
Looked online it's usually £13:99 (in the sale for £7).
It was the last one in the shelf but worth a look instore elsewhere
