Europe is truly unique in this regard. For instance, my father in law bought a Lithuanian made furnice from a retailer in Latvia because it was cheaper than if he would have bought in Lithuania. Car reimport exist as well,where a German would buy a car made in Germany from a Lithuanian dealer and transport it back to Germany,because it's cheaper. There are some companies that import medication, repackage and sell abroad in markets where the same medication costs more( this one is an old one,not sure if it's still the case)
