Purchase History helps you to keep a record of the orders and payments along with the details of the products.
To view orders that you’ve placed, go to Purchase History in My Account menu.
You'll find everything you've bought recently - and whether you've paid - in your Purchase History.
The purchase history includes date and amount of each purchase, as well as download links to each file.
Click "View Details and Downloads" to download the document you purchased. Links in the bottom are the file download links for re-downloading past purchases.
