How do I create a Buy X Get Y discount in Zoho Commerce?

Buy X Get Y lets customers receive a set quantity of an item at a discount, or free, when they buy a set quantity of another item.

Go to Marketing > Coupons and click + New.
Under Apply as, choose Coupon (customers enter a code) or Automatic Discounts (applied at checkout without a code).
Set Discount Type to Buy X Get Y.
Under Customer Gets Y, set the Receiving Quantity - the quantity of the item the customer will receive.
Set Condition Based On to specify whether the discount is applied based on items, collections, or categories.
Set the Discount Value as a percentage off the rewarded item.
Optionally, use the Restrict Coupon Based On section to:
- Enable Set Minimum Cart Amount to require a minimum order total.
- Enable Customers to restrict usage to specific customers or exclude guest users.
- Enable Eligible Shipping Zones to limit the coupon to selected shipping zones.
Fill in any remaining details such as offer period and usage limits, then click Save.
