Limit to one product of a specific category by order
I’m selling specific products that can only be ordered once per order.
Is it possible to tell Magento, for a specific category of product, that the customer can only order one item?
For example, the product is a membership with specific properties (6 months membership, 12 months membership), and there can only be one per order. All products are stored in the same category “membership”.
