Firstly i'd like to state that i have not purchased from this site. I was going to but after a series of correspondence I believe this one is not to be trusted.
When buying anything within the UK, you automatically pay VAT at 20%. So the price published on their site should include VAT. But according to Benshop, the price shown excludes VAT. This is not stated on the site but through correspondence this information was obtained from Benshop. So the question is if the item is delivered within the UK, VAT must have been paid, or it is assumed it has been.
They don't appear to accept credit cards only PayPal. But they show credit cards on their site as accepted.
