Ebay and paypal changed our system about a year ago, I now have tax added by them on every international purchase. 10% is the rate they decided on. The system just changed again in the past week and now some items seem to include that 10% in the total while others still add it as a separate charge in checkout. It really annoys me to have to pay on used items. I bought a used discontinued t shirt I really wanted last night. $14 bucks us ended up costing me $52 bucks to my door. I also have a running total of every transaction on ebay and paypal. One of the downsides of online shopping and the internet in general.
