Thank you for the replies and help to all who have responded.
In regards to what I am selling, my primary is gold and silver bullion coins. I do not sell guns as a dealer. I do not want the headaches of the federal licensing.
Secondary is knife sharpeners that are so good that my barber bought one because my straight razor is sharper than his, and I can carry mine in my back pocket. I do serrations and scissors too!
So how do the two find compatibility? Some shows will not let me in with gold and silver, so the knife sharpeners get me in and then I sell the bullion. It also helps to get people to stop at my table.
The valuable stuff is almost always with me. There are no intentions to leave it anyplace that can be dismantled by a battery operated Sawzall.
If you care to know more, I will be happy to discuss my products and reasons in private e-mails. This forum is not the place to advertise, if you know what I mean. No sense getting kicked out before I even get here.
