i want to make a situation which let users to buy products after adding them to cart when they are registered , and another group of people who got my coupon go throw the checkout without registration and login .
how can i do that ?

Hi,

You can configure the "Display method for registration" setting to "switcher" and the "registration" setting to both "registration" and "guest" to allow customers to be able to choose between login, registration and guest checkout in the "login" view of the checkout.
There is however no option to configure these parameters differently for different types of users.
