They have /an/ address.
Most of the large vendors have multiple physical locations. The "main office" is often not where the actual material is stored.
Amagi doesn't even have /an/ address. If they do please be so kind to point it out.
Liberty Metals Group has stores in California and Arizona and I have been to both. They have both addresses listed on their website.
AJPM has four walk-in locations listed on the main page on their website.
Gainesville has a showroom with an address.
I am confused as to why this is important? It IS 2013 afterall. Amagi is free to do business as they please. Amazed, do you travel all the way from the UK to pick up metals in California and Arizona?
