Buy the Nivea lip balm shown in the picture for £3.16p and get another one free. (BuyOneGetOneFree on suncare).
+ Get another (ANY) skincare item priced £3.16p or under totally free.
If its more than £3.16p, you just pay the difference. So effectively you are getting £3.16p off any skincare item.
This is due to the deal falling under the 3 FOR 2 on skincare offer aswell as the BOGOF on suncare!
Realised this at the tills when the person opposite me was paying for their shopping.
Possibly available online too.
