Hello – I’m looking to see if a coupon can be auto-applied if a certain item is added to the cart. So if this item is added, then the other item in the cart of a certain brand would receive 10% off, but not the trigger item.
You need a custom PHP snippet for that. The following snippet will only make the coupon valid if product with id 1234 is in the cart. Replace 1234 with the product id of the item that must be in the cart and replace THE_COUPON_CODE with the actual coupon code. Note: snippet has not been tested.
