You can set the minimum and/or maximum quantity of items that must be included in each bundle in order to add it to the cart.
To set the quantities, go to “Bundle Options”. If the value is set to 0, no control on the quantity will be applied.
The control on the quantity is given by the sum of the single item quantities added to the bundle.
The user will be notified by an error message in the product page in case the bundle can’t be added to the cart.
