Tea drinkers: Cut your milk spend in half just by switching to whole milk.
Like many people, I stuck to semi-skimmed milk in tea for years simply because it’s what my mum used and I assumed it was the healthier choice. Then I tried whole milk and hit a bizarre realisation: a splash of whole milk goes twice as far. You literally need half the amount to get the same taste in your tea, yet it costs the same per bottle. If tea is your primary milk drain, switching to whole milk literally halves your weekly spend.
