I have lately been thinking about selling sports jerseys, hats, window decals, shatter balls and some other items at our local sporting events, St. Louis Cardinal and St. Louis and Rams. I was going to buy the items through some suppliers I have found and take them down there and sell the on the corner outside the stadiums. What type of problems does this pose? It it legal? Do you think it would be profitable? Any thoughts or ideas would be great? Does anyone else do this themselves or know of anyone? Do I need a license or permit to do it out of my car?  Thanks in advance.
