E-junkie does not use ASP and does not require you to install any software on your server; E-junkie is "software as a service" that you subscribe to on a month-to-month basis. Once you set up your products in E-junkie Seller Admin, we provide you with ready-made HTML+JavaScript codes for your cart buttons, so 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.
Our system is designed to be really quite straightforward to configure and set up, and you have a fully-functional 7-day free trial period which begins as soon as you register for an E-junkie login. Our Getting Started help page is a good place to begin setting up your E-junkie service:
