I need to create a discount that would give customers the following.
Receive 25% off if you purchase an item from collection a and collection b.
i.e. if you are purchasing 1 chair (collection a) and 1 ottoman (collection b), then you will receive 25% off both of these items.
The basic shopify functionality does not have a way of specifying the customer must purchase 1 item from each collection.
Thank you in advance for any feedback!
