I dont know if it would be a continuous form of income, but it could start as some extra (non tax) income on the side. The places in CA where I've seen them are swap-meets, certain areas of the beach, and parks. I think any place where a lot of people gather would be a good place. The only thing about the swap-meet is that you would have to pay for a spot.


Maybe FB and craigslist can be options. The city where I live has a FB page where people sell stuff to each other. The only thing is that you have to be more cautious with these options.
