Brompton is a British company. Being British they believe they're from a large country and have no idea how to deal with sales and marketing to the United States, which is a large country.
I once contacted Brompton about their faulty dealer locator on the website. The problem is, it gives a town but no state, Mt. Airy USA is not a location, Mt Airy, NC and Mt Airy,MD are , and they have a store at one of these places. I e-mailed and attempted to explain the problem, they just couldn't understand. So it comes as no surprise that they would locate in a certain area and then market it badly.
