bear in mind also, that Amazon, like many multinationals are structured so that they make no, or very little profit
in the Uk. no profit - no tax , so probably no VAT.
Plus, there's a reason why they shipped those CDs & DVDs to you from Amazon Jersey, and why so much stuff is booked via Amazon ( republic of ) Ireland.
They will have an army off accountants figuring out how to offset all the VAT from amazon sales with VAT paid on amazons own purchases - desks, chairs, toilet rolls. The only cost is the accountants payroll
e.g.
Amazon has revealed that its UK corporation tax bill almost halved to £4.5m last year, days after the US company posted a record profit of $2.5bn (£1.9bn) in its most recent quarter
