But there is a difference between a "vendor" and a "member" that is willing to "sell" what they have. In my mind a "vendor" is someone that is in the business of selling. Ex. A merchant...One who is "in the business" of producing and selling merchandise.
A "member" selling, to me means someone that is not "in the business" of selling, but will sell when requested to do so....ie: isn't necessarily "licensed" as a business.
