I buy a lot of gear online and it often surprises me how often vendors do not deduct the sale tax when they are exporting, which results in you being taxed twice as you will be taxed by your home country when the goods arrive at the border (unless we are talking about the European Union)
We only charge VAT where we are legally required to do so, which is for any sale to an address within the European Union
Our website is sophisticated enough that if you are registered for VAT in a European Union country (other than the UK), you can enter you VAT registration number and accompanying details and we will verify that information against a third party website. Assuming you pass verification you are then able to purchase the goods from our website without being charged VAT and without the need for us to invoice you manually
