I see lots of issues with this. First off the 2 larger distributors in the US will only sell to somone who has a retail business license in thier state/county and a retail store front. Second is there are alot of flying sites that are operated on county/city/state property and are only able to operate as a non-profit. Selling hobby goods onsite would be a conflict of interest. And lastly. We need to start supporting our local hobby shops before they are a thing of the past.
