Thank you for your reply. For subscriptions, the Word Press Pro Membership add-on is fine, but for the composition of the download list, Word Press PDF Viewer is not what I am looking for. On my site currently the user can download the cards one by one.
What I would like to include is the possibility for the user to select the cards from an image grid and once the selection is finished download all the files at once. In short, it is as if the customer were composing his own book with the pages he is interested in. In the list of your add-ons I saw “Package Lists/Collection” and “WPDM – File Cart”, which of the two is best suited to my needs?
Thank you
