Whilst out hunting for a new laptop, I happened upon some in Staples. The one that caught my eye was nothing special - but it had an offer that baffled me.
It read: Sale! £299.99 Was £279.99!
Now, I'm a teacher, not a maths whizz (but actually...!) but even I had reason to pause...
Today's question: how many of these units should they expect to shift with that marketing ploy?
