I needed a photo frame and wandered into what looked like the right sort of shop. I didn't see a photo frame but I did see a clock on a suction pad which I thought might be useful stuck to our fridge (now that I've thrown my cooker out I have no kitchen clock). The suction clock was £4.
On the way to the till I saw some antlers shaped like mirrors which I had no idea I needed, I couldn't see the price on them so I took them to the till. On handing them over I noticed a ticket for £22 stuck on the back of the packet of antlers. At that moment the man at the till said
those antlers are 50p
Gosh, I said that's good do you have any more?
the man checked the computer and said that technically the one I had didn't exist and in fact the till price was not 50p but -50p, he rang my purchases up and I paid £3.50.
Bargain!
