That won't be difficult at all! You can combine all of your various audio files for each chapter into one single ZIP file for easy uploading/downloading. From there this would work out like any other downloadable product.
For a complete breakdown on getting started there are three main steps:
First, you need to set up your payment processor so you can make sales. If you are using PayPal that's as easy as entering your PayPal email into your E-junkie profile, otherwise there are specific instructions for each system we support here:
Second you need to set up your products. Downloadable products are very easy, the default settings we have turned on when you first open the "Add New Product" screen should be all you need... just enter the product's name, price and make sure the "Single File Download" box is checked so that you can upload the ZIP file that contains all of your chapters. Our help page on File Downloads has step by step instructions on uploading files:
Lastly you just need to add the HTML code we provide for your product's button to your website:
We have two types of button and you only need to pick one of them. Our Cart buttons work well for merchants who have more than one product or need to use settings like shipping costs or sales tax. Since you have one downloadable product you may be interested in the "Buy Now" button instead, which skips one product straight to checkout for easier ordering.
Just copy and paste the code we provide into the HTML of your website and you're ready to go, your buyers will be able to pay you directly through the payment service you've set up and once we get notice of the completed payment we will provide a download link for your audiobook.
