I am using multisite, that is, the subsites / subdrectories are all from one WP install.

You mentioned that it should be possible to achive in using multisite. My question is coming from, paypal settings etc. have only one URL that I need to enter in the settings. Shoudl this be the primary domani?

If yes, it appears that all payment needs to be processed from the primary domain, which I can, but how do I grant access to a user to site.com/product1 when site.com processes payment for product 1, grant access to a user to site.com/product2 when site.com processes payment for product 2, etc/?
