Well - if you like big Cities and lots of people around - That's fine. I had my fill of all of that when I was working for a living - and used to go into "HQ" periodically in the City of London. Loved the convenience of "The Tube" - but hated the push and shove of too many people in too confined a space.
Knightsbridge, of course, is a rather swish address nowadays - and anyone running a Toy Soldier business from there - has to be able to manage the associated property costs involved - which do impact on the prices they have to charge for their products.
I much prefer the open spaces nowadays - and the less busy and quieter life involved with living in the country. The Internet has also meant that "The Toy Soldier Shop" - rather than in bricks and mortar, can be virtually anywhere, ( A "virtual shop" in fact). All you need is an e-mail address - and a reasonable postal service - and you're off.
As stated though - you can't really beat the personal visit - to see and explain just what you would like to do. That's why I value my "annual" visit to Dorset Soldiers. Incidentally - if you want a view of Giles' shop - just access his excellent web-site - and click on "New Shop" for a pic. It's in Fortuneswell - at the foot of the hill near the harbour - so a nice place for a visit - and a stroll with an ice-cream later on. La Commandante enjoys that part of our visits the best!
I would also recommend a nice tin of chocolate biscuits for your local "Postie" around Xmas time - not exactly bribery - but the cheapest goodwill builder and insurance for your packages that I know.
