In my local supermarket, a bottle of own brand lemonade has been 27p for the past year.  When I went to stock up for Christmas - just a few days before the great day, I discovered that it was now 42p - a rise of 15p or 55%!!!!!!!!!!!!!
Was there a great shortage - had there been a run on lemonade all over the nation.  Well it didn’t appear so, stocks seemed to be just as plentiful as ever.
So it got me thinking that it was just a great big Christmas supermarket rip-off.  They’d seen me coming and in future I’d have to buy ahead.
Well, I’ve been waiting for it to come down in price and it hasn’t.  So what’s going on here.  I’ve looked at the price of lemons and that hasn’t changed, neither has the price of plain water.  So clearly the price is not in any way related to the cost of the materials.  It seems to me that it’s a made up price - charge what you can get away with, charge what people will pay.
I’m not sure how I feel about that.
