Differences between rule Product limit vs Collection limit vs Order limit

Here is the clear explanation of the differences between the three quantity-based rules in the app:

Product Limit – Limit per individual product

This rule applies directly to a specific product.

You set the minimum or maximum quantity that customers can buy for that product alone.

Example: Product A → Max 2 units The customer cannot add more than 2 units of Product A, regardless of what else is in the cart.

Best for: – Limited stock items – Products that require strict control per SKU

Collection Limit – Limit shared across all products in one collection

This rule applies to an entire collection.

All products inside that collection share one total quantity limit.

Example: Collection “Sale” includes A, B, C Limit = 5 units A customer can mix products, but total quantity must be ≤ 5. For example: 3 × A + 2 × B → Allowed 4 × C + 2 × B → Not allowed (total = 6)

Best for: – Flash sale collections – Groups of products that should follow the same purchase restriction

Order Limit – Limit for the entire cart

This rule applies to the entire cart.

You set a limit for the whole order, regardless of specific products or collections.

Example: Limit = 10 total units in the cart. Customers can mix any products, but the total quantity must not exceed 10.

Best for: Controlling overall order size and preventing bulk purchases.
