I have a client that sells gym equipment and workout programs. I want to make it so that customers can only add & checkout with one workout program at a time, with a max. qty of 1 per checkout, but they can still have multiple products from other collections such as gym equipment. Is there a way to do this?
You can consider using a third-party app, like Order Limits (MinMaxify), to set minimum or maximum quantities on collections, product types, or tags. If you need to get help with a third-party app, then the app developer is always available to assist you. Simply reach out to the developer using the contact information found at the bottom of their app’s page.
