Dear Customer

Thank you for contacting Amazon.co.uk with your enquiry.

I'm sorry for any confusion caused in this case.

In accordance with the laws governing members of the European Union, Amazon.co.uk is obliged to 
charge VAT on all orders delivered to destinations in member countries of the EU.

For all orders and deliveries that we send to "Lithuania", we are obliged to charge VAT at the local 
rate. Your local VAT rate is 21%.

The 15% rate you have been informed is the UK local rate.

Our prices listed on our website are inclusive of the British VAT rate. When you purchase an item on 
our website, the price you see initially is the price that includes the rate of VAT applicable 
within the United Kingdom. If your order is marked to be delivered to another member state of the 
European Union, we will re-calculate the price
during the checkout process of your order by taking the price of the item, excluding UK VAT and 
adding VAT at the rate applicable in the EU member state. Since VAT rates differ widely within the 
EU, the final price of your order will often change to reflect the VAT rate that is in place in the 
EU country of destination.

If you wish to determine the price you will be charged for an order that has a delivery address to 
"Lithuania", or other country within the EU, then please view the order summary section of the order 
form where your VAT charges will be itemised. As soon as a delivery address is associated with an 
order, it is possible for the correct VAT charges to be calculated.
