I was in Tesco yesterday and I was looking for lucozade for my poorly son and found Tesco have brought out their own version (called Active) and its only 30p for a litre bottle! I bought 2 orange and 2 original with B vitamins for £1.20.......about the price of 1 bottle of Lucozade.
He says it tastes as good as!!
I think its maybe a new product promotion so may go up to full price anytime as its 70p online.
