They have to ship the engine via the US Post Office or Fed Ex or UPS or maybe DHL. But that means the seller has to go to the shipper's office to drop the package off. Most ebay sellers just, go with the flow so to speak. I haven't tried shipping a model engine overseas for a long time now, so I am not sure if any of the other methods don't work now or not. I usually ship via the USPO here for everything.
