Apart from discount codes, you can use Volume Discounts in Cvent to implement a Buy One, Get One Free (BOGO) offer.
1. Go to Discounts in your event and select Volume Discounts.
2. Set the Threshold to 0 (so the discount applies immediately).
3. Select "Subtract a percentage" as the discount method.
4. Set the Percentage to 100% (to make every second registration free).
5. Apply the Discount Repeatedly at an interval of 2 registrations (so every second attendee is free).
This way, when two people register together, one is automatically free without displaying a 50% discount.
