Adds the VHX Checkout Embed to your site to enable a seamless checkout experience.
Any link on any page pointing to http://yoursubdomain.vhx.tv/buy or http://yourfulldomain.com/buy will be picked up by the checkout embed. Whenever someone clicks on those links will automatically slide out the checkout form to purchase on your site.
Additionally, you can additionally set specific data-vhx-site attributes on individual links to override your primary one set on the script tag. It looks like this:
<a href="http://drafthouse.vhx.tv/buy/the-final-member" data-vhx-site>Buy This Movie</a>
