World trade market issues

If I’m not mistaken, the way the marketplace works is when you put stuff in it to sell if you don’t advertise it by paying that dollar or the one free one they give you usually every like a couple of minutes, that your items are shown to people in your club I’m assuming if you’re in a club but when you advertise it, they show it to a more global market if you will and the items tend to sell that way and faster too.
 at least for me that is.
