I absolutely love having street sales, my sim always makes a TON of money. I haven't sold anything with the table, but I have with the display canvas for her paintings. It's actually really fun and I love that the display is portable and she can start a sale anywhere in the game :) I agree, it's one of CL's coolest features and I don't think very many people even know about it or how to use it properly. I remember having to Google how it worked before I figured out how to use it, haha.
