"Single mother-of-four reveals how she feeds entire family for £3.09 a week using anti-food waste apps - and even has enough produce left over to donate to food banks and care homes"
That sounds like bollocks to me.
"I used an app called Olio. This is an amazing app with some really truly amazing people - they either give food away from their own homes or collect from businesses such as Costa, Pret, Booker and Tesco to list on the app."
Oh, so it was bollocks - she gets given free food from elsewhere, ie. other people are paying for her and her 'entire family'.
