Module for managing permissions on per node basis integrated with shopping cart or checkout Hey I'm looking for a way to manage specific users access to specific nodes in Drupal. I'm wondering which modules I can use to accomplish this. 

To elaborate:

Lets just say I have 20 stories on my site that cost 5$ each to access. Users need to sign up, and then they pay $5 for each story they want to have access to. 

I need to manage the individual user's access to specific nodes automatically after they are paid for...

Anything you can point me toward would be helpful

Thanks
Content Access module restricts users per node basis or per content type basis.


  This module allows you to manage permissions for content types by role
  and author. It allows you to specifiy custom view, edit and delete
  permissions for each content type. Optionally you can enable per
  content access settings, so you can customize the access for each
  content node.


You need to use commerce checkout hooks and Content Access API to achieve this. Try rules modules too it may help with out using coding also.
