I guess this question is for those familiar with selling from state to state, in the USA. Let's say I want to travel from gun show to gun show throughout the US, selling gadgets and whatnot. I know I will have to make certain Uncle Sam gets his cut, as that's as inevitable as anything is. But what about state taxes? Let's say I travel and makes sales in 20 states during a year. Do I have to collect taxes in every one, and then pay the many states their respective share?
