System Requirements

Hi
I want to buy the pro version.
I saw a way to acquire all the credit cards and not just PayPal.
The site I am building is a courses. A user logs on to the system and may buy a single course.
1. Is it possible to add a coupon code for a course?
2. Can he see the courses which bought in personal user page?
3. Do I post registration and login page in the format of the site?
4. Do you give me a discount coupon for the purchase version?
