Why have I been charged VAT at checkout on top of the purchase price given on ebay page

[solo-silver]

Why have I been charge VAT at Checkout on top of the Purchase price shown. I cannot see any mention of Vat being added anywhere.. It is supposed to be coming from Leicester. I have since discovered that the owner's listed address is actually China though I suppose he may have a warehouse in Leicester.
Its the VAT thing that is annoying me. It is misleading to say something is 6.50 then when you pay it is VAT on top which I did not notice until after I had paid.
I thought VAT was included on everything sold on here with free postage included and Purchase price was the Final price.
If this is going to happen on everything I buy buy, then I wont be buying much. It then makes it expensive with another 20% on top
Does anyone here have any information on that please

It doesn't matter if the item location is in the UK.

It's the business sellers registered address as this is where the transaction was made. In your case the item was in a UK warehouse but you didn't buy from the warehouse, you bought and paid from your seller in China.

The only argument could be that eBay say all items on eBay UK must include VAT in the price displayed.

But the small print on listings state buyers are responsible for taxes etc.
