In order to help you sell your eBooks from your website, Ted Weinstein Literary Management has built a widget that you can use to add a “Buy this book” button to your site. The button will feature a number of retailers that sell the book, so that readers can buy from their preferred vendor.
The agency lists their terms on their website: “You are welcome to use this widget on your own website, although we cannot offer warranties or guarantees or tech support of any kind. If you have affiliate accounts with any of the major online book retailers you can insert your IDs in section #2 below so you earn your own referral revenues. If you do not — full disclosure — then our own affiliate codes will be included. Seems fair, yes?”
Follow this link for the four step process that you will need to follow to add the button to your website.
