Normally, once you set up your products in E-junkie Seller Admin, we provide you with ready-made HTML codes for your cart buttons. You would simply copy the codes from us and paste them into the HTML source of your own Web site pages, wherever you want our buttons to appear among your own layout, text and images. This is how the vast majority of our sellers use E-junkie to sell online. See more details about our button codes here:

However, if you don't have your own Web site or don't wish to paste our buttons into your site, you have the option of posting product listings to your own E-junkie Shop page on our site, listing your products at a specific URL where you can send buyers (http://www.e-junkie.com/37 for example). Listings from your E-junkie Shop would also appear in the general E-junkie Marketplace once you start a paid subscription. This help page explains more about posting product listings to your optional E-junkie Shop:

The Marketplace primarily just provides a way for search engines like Google to find your products, if you don't have a site of your own that they would normally find otherwise. E-junkie Marketplace is not a major shopping destination site like eBay or Amazon; buyers don't really come to our Marketplace and just browse around looking for things to buy. Most sales in Marketplace happen because of search sites like Google sending buyers directly to a specific product page, or because the seller's own ads/marketing sent buyers directly to their E-junkie Shop or product page, but this would be a distraction from your own Web site if you prefer to sell primarily from there.
If you prefer to sell from your own Web site, you can just disregard listing products in an E-junkie Shop page. Our Getting Started help page is a good place to begin:
