How to sell product on the net please advise..

What kinds of products are you looking to sell? There is Etsy for homemade or vintage stuff. There's Ebay but that's really only helpful if you have something people want... I even tried selling a pair of jeans that I never wore but that I'd found out from someone who worked for the company were still very sought after even though the company didn't make them anymore... I thought hey! I have them, someone might want them, they can't get them anywhere else anymore... no dice. Didn't even get one bid... so that's definitely a source for people who have things other people want. My friend just started fiddling with a site called Listmania. I'm not at all sure how it works other than it's an auction site like Ebay. But it's something to check out. Or if your "products" don't fit any of these sites, get a cheap domain and hosting and set up your own website then promote it like crazy.
