Caterham,
Unfortunately in most situations localities dont allow you to have a business license in your residence and conduct physical transactions on the premise (meaning have your doors open). However, I have heard of cases where it could be done by appointment. Believe or not, this industry is fairly competitive and at times, at least in Richmond, petty, and the certain local stores will do what they can to squash you. I am looking into whether or not I might legally be able to have people over by appointment.
Oldgrayhair, thanks for the info, I will definately make the call, those plugs are awesome
