According to the Chartered Institute of Tax the impact of the VAT change on a household with earnings of £20,000 a year is £2.50 a week.
Sorry: but that's ludicrous. It's not enough to deliver change.
And that assumes the VAT saving is passed on, and it won't be.
I suspect this is a horribly regressive reform: the benefit will pass to the shareholders of retailers in increased profits.
