I'm trying to work out a Drupal Commerce build which is my first attempt at using it to sell a product.
Rather than selling a physical object I am trying to sell access to a link (I have already planned for an 'authorisation ticketing system' to ensure that you can't just copy the link address, you have to come from my site) but I am getting confused because I am not selling a physical object which you can buy more than 1 of, nor is it a digital file to download - basically my goal would be that when you have bought access to the link, the 'Add to Cart' link on the page would change to 'View' and then this would be the link you bought.
Also, I fear that during set up I have been missing some key principles of how Drupal Commerce works, mainly the confusion is surrounding products/product displays. When do I add fields to a display and when do I add them directly to a product? My initial thought was that it is kind of like how 'Argos' works, you can add products to your site in the same way they would be added to an inventory, but they are not displayed to the public - only when you add a display (like how Argos add displays to their catalogue) do the public have the ability to browse and view the product. Is that right?
