Seems it's a 'USA only' market place [kits] (Guess that's a gripe more than anything, and seeing that the USA is 90% of the site / www...)

Sort by 'country shipping to'...

I was also trying to find info on being a 'commercial vendor' Couldn't find any. Also, while looking though the 'sign up'; it's one of those 'fill this out, then fill this out, then supply these numbers'.. No real 'overview' of what is required and the type of steps you'll be asked to perform. But I guess that's a typical 'web thing' too. We all have it..
