My Black Friday shopping memo...
If you were going to buy it anyway and it's half price, you've saved 50%.
If you weren't going to buy it, but do because it's half price you've wasted 100%.
@MartinSLewis@bbc5live Whilst in full time education absolutely not. However if they come back to live at home i will be charging them 45-50 per week rent and money towards bills food shopping etc.
