I want to start advertising my products on the Marketplace by featuring them on the category landing page. Truthfully, I'd only need to sell about two of the item to make it profitable, but what I want to know is, does advertising REALLY make a difference in the number of products you sell? I know more people would see it and stuff, but what are the chances that someone is gonna stumble upon my particular thing in the featured category? So, I just want to know if you think it's worth it. Opinions?
