Collection Limits

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.
