All taxes and shipping are collected upfront by eBay and paid to eBay and I cannot change this quote as it is calculated by eBay.
Once the item arrives at eBay in the UK, I no longer receive tracking updates so I cannot provide tracking updates beyond this point and eBay will need to provide this information directly.

If you have any questions about international shipping, please contact me and I will reply as soon as I can.
