A chocolate bar, featuring mould and dirt after spending far longer than its edible life squashed between the cushions of someone’s sofa, has sold for more than £200 on Ebay.

The Wispa bar, now extinct from the chocolate world, was put on the internet auction site five years after its best before date and fetched the ridiculous sum probably by someone searching for a bit of sweetie nostalgia.

There are now 62 Wispa-related items on Ebay, including Wispa phone cards, Wispa T-shirts and eight Wispa mugs. ‘Mug’ being the operative word.

Aside from being keen to know what Mr Wispa-buyer plans on doing with his rather expensive inedible extinct chocolate bar, I just don’t get what possesses people to spend their hard-earned cash on useless dust-collectors.

But there must be a market for it. My investigations on the world’s largest online auction site found 38 ‘useless’ items, 13 ‘pointless’ items and two ‘aimless’ items. Nothing was found when I searched for something ‘insignificant’ though.

And it has just emerged that a glass of two-week-old urine in an Ikea glass fetched £75. (Ikea glass to be sold separately). If that’s not bad enough, half a Kit-Kat allegedly once sold for £88 and an old two pence piece fetched £325.

Clearly I am missing a trick here. I’m a stickler for best before dates, refusing to eat food even a minute after its date of departure from the good-to-eat world. Usually I throw it away or feed it to my less-concerned other half. It’s just something I find hard to escape; buying more than you can plough through in a week and having to throw it away before the next shopping load needs that fridge space.

But perhaps instead I should ebay it and make enough to pay for the next shop. And if all else fails I’m not going to rule out the possibility of selling my own Ikea glass. Minus the liquid of course.
