Documents can be purchased once you have clicked into a case and scroll down to the Events section.
Directly to the right of the document will be an Add button.
Click the Add button to put the document into your cart. The cart icon is located at the top right of your screen. The number on the cart indicates how many documents have been added to it. Click the cart to review the purchase.
You will then be redirected to the Shopping Cart page. This will allow you to review all the documents that were added, select the proper Payment Method and click the Buy Documents button.
Documents will be emailed to you shortly. You can also navigate to the Purchases menu located under the menu at the top left of the screen.
