You can now validate cart quantities per line item with the new Quantity per each product condition in validation rules.

This lets you block checkout or show a validation message when any single product quantity is too high or below your required minimum.

For example:

• Limit bulk purchases by blocking checkout when any product exceeds your maximum quantity

• Require minimum quantity per product for wholesale or bundle-style offers

• Set product-level quantity checks without relying on product tags

• Use simple quantity thresholds with greater than or equal to / less than or equal to operators

This gives you more precise cart control and helps enforce quantity policies before checkout is completed.
