Specsavers customers shocked when he was asked to pay more than £4billion for a bottle of eye drops.
Cameraman Martyn Chidlow went in to buy the bottle of drops at the store in Wrexham, north Wales, to stop his eyes getting dry.
But he was shocked when the price of £4,031,626,711.51 popped up on the till – the equivalent of more than half the annual NHS bill for Wales – instead of the expected £9.95 price.
‘I couldn’t believe my eyes’
The 55-year-old, from Wrexham, told the Press Association: “I’d recently had my eyes tested and I’d popped in to get the prescription and to get the eye drops because I get dry eyes.
“The girl scanned the drops and then she was having a bit of a nightmare as she scanned it again and this price popped up.
“I couldn’t believe my eyes when I saw the price on the screen, I’m glad I’d just had my eyes tested.
“I said to the assistant ‘I was going to pay by cash but I guess I’ll have to use my card’.
“I caused quite a stir as I just started giggling, I felt sorry for the lady at the till as she was trying to sort it out.
“She was really good and got it all sorted very quickly. It wasn’t human error, it was just a problem with the computerised till.
