The Paytable widget is a mini version of your product landing page that can be placed anywhere on your own landing page. Below is a quick video showing how the example database is placed onto a JSfiddle page but the embed process is exactly the same no matter which platform or site builder you are using:

• Grab your embed code found in the 4th step in the product builder
• Place that code into an html block in your site
• Your widget with both checkout and login links is now active

Notes:

When embedding the widget into your own site, the links 'breakout' of the frame (because it is embedded and redirect the user to the correct page).

If you're looking for more flexibility you can just use direct links from buttons anywhere on your site. See option 2 in the embed tab, where you can grab your direct links.
