You'll find a new option when purchasing courses, called Course Coupons. Course Coupons enable you to purchase enrolments for a course which you can use at a later date without having to enter learner details upfront.
Course coupons are enabled by default, but can be disabled on the Course Settings page of a course. When purchasing course coupons, they'll appear on the new Course Coupons tab of your profile. You can redeem them for an enrolment by browsing to the course the coupons were purchased for, clicking Enrol or Purchase for Others, and selecting course coupons during the checkout process.
