it was invariably stuff like "you can save lots of money by buying cheaper brands, or even supermarket versions!!!"
"don't buy four times as much as you need and then throw most of it away!!"
"try cooking in batches!"
and at the end was always the big reveal of WOOOOW look how much you saved per month, and the "savings" were double what I have ever spent in my life, because they were having twelve takeaways a month and falling for shit like £6.40 for 200g of premium individually bagged moravian oats
