Pennychews hit by global recession

For those who don't know a 10p mixture in Scotland is traditionally a bag of sweets to the value of ten pence. A pennychew is a sweet worth one pence and usually there will be a couple of sweets worth 2p and maybe one worth 5p but it all adds up to ten pence and the economics are pretty simple even to a mathematically challenged person like me. That all made sense until my friend Mark told me that he recently went into a shop and noticed, I imagine, to his bemusement that a 10p mixture actually cost 20p! I know this is a time of global recession but this must be the worse case of inflation that I've heard of. 10p mixtures were part of my boyhood and I can't help to think of them without a hint of nostalgia, so it's sad to see the day when a pennychew is no longer a pennychew.
