I'm partial to those RockStar energy drinks - sort of Red Bull meets fruit juice. Widely available in every corner shop for 99p. In fact, the can has 99p printed all around the top.
Couple of weeks ago, saw them in Tesco, without the 99p printing, at £1:39! That's 40% over the going rate!
What a surprise, today in Tesco they are on offer at £1, "save 39p".
At least Dick Turpin wore a mask.....
