Product listings in your E-junkie Shop are always arranged in order from newest to oldest, according to their last-updated timestamp. To arrange product listings in a certain order, edit them in the reverse of that desired order (I don't think you need to actually change anything, just go through the listing details until you can click Submit to update).
However, if you are primarily selling products from your own Web site, there's really no reason or advantage to post optional product listings to an E-junkie Shop as well. 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 E-junkie sellers use our service.
If you don't have your own Web site or don't wish to paste our buttons into your site, then 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). This help page explains more about posting product listings to your optional E-junkie Shop:
Once you start your paid subscription for E-junkie, product listings from your E-junkie Shop will also appear in the general E-junkie Marketplace. The Marketplace is not a major shopping destination site like eBay or Amazon, so buyers don't really come to our Marketplace and just browse around looking for things to buy; it 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.
