Tellwell will list the purchase links of the major online retailers selling your book on your website (see example). This is the best way to fulfill orders for your book as online distributors and retailers process, print and ship the books on your behalf. It's important to note that sales via retailers count towards bestseller list rankings, whereas sales via your own personal website would not.
Some authors, however, may want to sell merchandise or services related to their book and that is where integrating e-commerce into your author website would make sense. Once your author website is completed, we will pass on the login information to you and you are free to integrate e-commerce into your website.
Two popular e-commerce plugins for WordPress are WooCommerce and Shopify. WooCommerce is free, whereas Shopify charges a minimum of $30/month to use the service (plus an additional monthly fee for the WordPress plug-in).
Here is a list of video tutorials explaining how to set up WooCommerce on WordPress.
Please note, it's important to keep your e-commerce plugin and WordPress theme up to date, otherwise, they may malfunction.
