So if a person purchases product A (a physical item we ship to him), can he automatically be added to for instance couse #2 and get access to all that material?

I want to have a system in place where my customers get access to a "product buyers only video course" on how to use our products the best way.

Can I do that easily with this plugin, without bundling this product with every product I sell?

Can I for instance create a free course that everybody get access to as long as they have a WP user?
