Or she could have just used trolley.co.uk where you can enter the product and get a detailed graph of the price over the year, and can even see the price changes in the different supermarkets. I don’t think Jack understands how data works though.One of LBC Radio’s presenter does a weekly basket update. They costed a basket of items a year ago (bread, milk, pasta, bread, butter, chicken etc) and every week they do an update on the cost. I think this week it was £15, she they started it was £9 (rough figures as can’t remember exactly ).
It is so simple and effective in talking about the cost of living increase, minimum input with a clear output. Jack could have done something like this, updated Twitter and made her point without having to triangulate a few hundred faded receipts from random punters around the country!
