There are a number of other non-USA countries, in South and Central America and elsewhere, that use US voltage standards or something close. I haven't checked prices, but in some of those countries Festool prices may be much higher than in the USA, and/or lack a convenient dealer network for the brand.
I presume people from the Caribbean, Mexico, or South America may purchase from ebay, and have the items shipped international, and possibly still get a better price, or quicker delivery than they might purchasing from their home country.
