Went in to Bournemouth Tesco Extra and they were selling their own brand of sugary energy drink for 30p a litre. In my opinion it tastes exactly the same as the lucozade stuff. They were selling original and orange flavour.
Not sure if this is online as well but I bought a few bottles omnomnom. It didn't have a glowing yellow deal label but instead had a white one with 'NEW' written next to it so I can only assume they are re-launching it with new packaging because the old stuff disappeared for a while.
