Bah, I hadn't even thought of the cost when they whack "energy drink" labels on things. £1.59 I assume is for the 500ml bottle, what a pile of turd. Probably is the same thing but they know theres fans of the drink so can fleece them for added cost.
As I said earlier, bunch of retards, fans of the drink have told them EXACTLY what they want reintroduced back in the UK so they've decided to go and release something different at a ridiculous cost, though admitedly, cheaper than importing cans.
Maybe a campaign of anger at them on their facebook page all requesting the normal(and diet) versions of the drink are reintroduced in the UK at normal soft drink prices.
Might see if I can't get a few at £1 for the novelty and hope its okay tasting, but at £1.59, i'll probably return to buying a 24 pack on/around my birthday every year as a treat.
