If you weren’t going to buy it, but do because it’s half price you’ve wasted 100 per cent.’The annual consumer event is derived from the post-Thanksgiving US tradition. It often marks one of the busiest shopping days of the year, and sparks vehement criticism for its encouragement of over-consumption and potential to inflict severe environmental damage.Mr Lewis’ warning comes as he prepares to host the new series hisThe Martin Lewis Money Show Live, broadcast on ITV every Tuesday from 8pm to 9pm.The programme is now into its 12th series and celebrating its 10-year anniversary on the air.
