Just been instore at Laindon Tesco (Essex) and all their own brand sun protection seems to be discounted heavily. Available in a standard bottle for 75p (I think it was 200ml) or in a spray (definately 200ml bottle) for 82p. I purchased the spray versions of aftersun, SP15, SP25 and a "Sensitive" SP30. The SP25 was also available as a Clear Spray. Oh not sure how much it usually is but next to the sun cream was a Tesco Insect Ease Spray (50ml) down to 75p. Pretty sure they had kids versions available too but didn't take much notice of that as I don't have any.
