I saw this today and bought the 20spf in sainsburys. they are 150ml and come in 15spf, medium 20spf and high 30spf.
I was surprised to see how cheap it is! all the other ambre solaires were at full price of £12.99 ie the clear spray or lotion,but the clear gel were all £3.24!! i thought id inform the rest of you incase you wanted to top up on you sun creams, i think its a pretty good deal. much better than paying £12.99! even in the summer other deals of BOGOF are still expensive!
these are currently £12.71 in boots, and £13.21 in superdrugs.
