I was in Tesco in North Berwick, near Edinburgh, today and bought some sun lotion for the scorching weather I'm hoping comes along this summer!
Anyway I was going to get something cheap but spotted Riemann P20 (100ml) for only £6.48 which is very cheap compared to what I've paid previously for this (I think it usually sells for about £13 a bottle this size). The shelf label wasn't yellow so didn't appear to be a special offer, but this looks to me to be pretty much half the normal price.
Also just checked online where it does show up as being half price down to £6.48.
Hopefully this helps someone who was planning to buy this for their summer holidays.
NOTE that this offer expires on 10th May so you'll need to get it delivered or buy in store by Sunday to get this deal.
