Collection limits let you cap how many items a customer can buy from a specific collection in a single order. This is useful when you want to restrict purchases across a group of products rather than setting limits on each product individually.
Setting Up Collection Limits
Go to Rules and click Create rule
Choose Collection limit as the rule type
Select the collection you want to limit
Set the maximum items a customer can buy from that collection per order
Save the rule
Use Cases
Limited editions – Allow only 1 item per order from your “Limited Edition” collection
Sample packs – Let customers pick up to 5 samples from your “Samples” collection
Fair access – Limit high-demand product categories so more customers can purchase
What the Customer Sees
When a customer tries to add more items from the collection than allowed, they see an error message
The error explains how many items from that collection are already in the cart and the maximum allowed
At checkout, Shopify validates the limit again to prevent bypass
How It Works With Other Rules
Collection limits work alongside product-level rules. If a product has both a product quantity rule and falls within a collection limit, both are enforced. The stricter limit wins.
Plan
Available on all plans including Free (counts toward your rule limit). Growth and Advanced plans support unlimited rules.
