Bear in mind E-junkie is not a payment processor, so we do not handle any actual payment funds at any point. Buyers would pay directly into your chosen payment processor account, such as PayPal. In order to use our shopping cart and other features, you would need to have an account with at least one or more of the independent payment services we support:
Once you set up your products in E-junkie Seller Admin, we provide you with ready-made HTML codes for your E-junkie 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. Buyers will see a separate checkout button in their cart for each payment service you have enabled in your Seller Admin, so they can choose the payment method they prefer from among those you accept.
