A KFC fan spotted an outrageously good deal on its ordering app which meant burgers were for sale for 50p each.

The finger licking discount was thanks to an error, but some customers saved more than £4 on certain menu options.

Zinger Tower Burgers – which contain a chicken breast fillet, hash brown cheese and salsa – usually costs £4.59 each.

However, on Monday foodies grabbed theirs for less than a quid.

One customer said: “I just bought 20 fillet burgers from KFC for £10. I can't believe it!"

“Go go go, 50p Tower and Zinger Burgers via the KFC app,” added another.

Cheeky KFC lovers spread the news on social media, where on Facebook group said: “Fast food lovers have been ordering up to 20 chicken burgers each from KFC today, after a glitch in its app meant they only cost 50p.

"The glitch was first spotted today at around 12pm, with KFC fans quickly sharing the news and encouraging others to make use of the slashed price."

The App sold burgers for just 50p

One bloke joked: "A tower of Fillet Towers.

"£2 bargain."

“Not bad for £5.50.” boasted another.

Unfortunately, if you were looking to stock up and freeze your favourite KFC meals you’re not in luck.

The error was corrected.

A KFC spokesman said: "What an 'appy Monday for some...

“Our Zinger Tower Burger and Fillet Tower Burger were priced incorrectly for a limited period yesterday meaning a few of our eagle eyed fans got the best Cyber Monday deal going.

"It's all fixed now though – take it up with admin!"
