I'm looking for an inexpensive solution to this problem. I need a shopping cart that will easily integrate with my existing Moodle site. The cart should allow the user (student) to browse all available courses and be able to purchase one or more courses. After the sale is complete the cart should then automatically enroll the student in the purchased courses at the Moodle site, using the same user name and password they used to register at/in the shopping cart.
Thank you for your time.
