Purchase Course or Product automatically add the course

Currently the selling of courses are done by integrating with MarketPress or WooCommerce. When we use MarketPress the visitors go to Shop page and see the course as product but when they click on the course title they are forwarded to the course page and there is not Buy button so to purchase it they need to get back to the shop page.
This works well when using WooCommerce but do not know if they enrolled automatically in the course upon purchasing. The user should be able to just go on to the site, browse courses, choose a course and enroll all while the owners of the website are sleeping.
All other WPMU plugins we use are so simple to setup and work great out of the box. So I guess the missing link with this plugin is...
being able to purchase the COURSE / PRODUCT and it automatically adds the course to the users account.
