Hi I have Purchased $230 (£180) worth of items from USA for Christmas present. Is anyone able to give me a good estimate on what the total charge of customs VAT I would be liable for . I think VAT is 20% of value of item but not sure how the customs charge works and as far as I know there's also a £8 postal charge from Royal Mail . Been told at post office I can use credit card to pay for this but want to prepare myself in case it's a lot more than what I've estimated it will be .
