Shipping even within the US has become significantly more expensive. And via USPS, generally slower.
There's not an easy shipping model on Ebay for International shipping, but that shouldn't deter Sellers, it can be figured out.
I have stuff on Ebay and have sold overseas, with only one problem from a dishonest buyer in 20 years.
Never heard of "Ebay Global"; I've always thought the whole thing was global; I've bought stuff from Europe same as if it was here in the US.
