Adding 'AddThis' sharing functionality to a Drupal Commerce Checkout page How can you add the 'AddThis' sharing buttons to a Drupal Commerce checkout page?

I tried adding an AddThis field to the product content type as I do for the other content types to wish I want to add this module but that doesn't seem to add it to all the pages in the Drupal Commerce checkout process.

If anyone knows how to do that that would be great. Thanks!
As you discovered in your comment, the recommended approach would be to have the AddThis block show up on the checkout/* pages. The question is: what are you sharing, exactly?

If you're wanting to include the sharing process as part of checkout, a new, custom pane would be the best place for this.
