The internet has gone mad over a simple trick to get extra sauce on a McFlurry.
McDonald's fan favourite dessert has, over the years, been flavoured by various chocolate bars - currently being Cadbury's Crunchie, Oreo, Flake and Flake Raspberry - however, the sauce used on the ice cream has been somewhat limited.
However, in certain branches across the country, fans of the ice cream dessert can ask for extra sauce as a measly price of 20p, the Metro reports.
This discovery has sent Twitter users into a meltdown with Tom Hyndman writing: ''You can get an extra shot of topping in your mcflurry for the low low price of 20p.
''Absolute game changer news this! (sic)''
Amy Ashmore also found this new trick to be the ''best 20p you will have ever spent''.
She wrote: ''I recommend when buying a mcflurry, always ask for extra sauce, it is the best 20p you will have ever spent #saucy (sic)''
A McDonald's spokesman said : ''We offer guidance around pricing, but ultimately our franchisees decide on those which are set based on a number of factors.
''We and our franchisees pride ourselves on providing good quality food at affordable prices up and down the country, and work to keep differences to a minimum.''
