Cheap but expensive

On the spur of the moment I bought a bag of licorice allsorts yesterday. I hadn't eaten licorice allsorts for years but liked them as a kid when they were half the size and probably twice as expensive. The ones I bought were large, beautifully formed and cheap but they were also inedible. Cheap licorice allsorts are an expensive way to fill your rubbish bin. 

They not only tasted disgusting, they smelled worse than new Ikea mattress I have airing out in my spare bedroom. Perhaps they both have the same chemical composition.
