My experience with shipping internationally is:
1. Too many buyers have asked me to mark the customs form as a "gift" after they bought my product. Cancelling a sale like this automatically opens one up for negative feedback.
2. Depite the weak US dollar, the VAT pushes up the overall price for what I sell to the point where buyers are turned off.
3. Shipments of coins across international borders tend to get "lost in the mail" and the ability to track a shipment beyond US borders is deplorable.
If anyone on the "other side of the pond' has different experiences, I would welcome hearing them. Otherwise, my margin does not allow for even one "lost" item
