Charge an extra fee when specific products are added to the cart together

This scenario allows you to apply an extra fee only when certain product combinations are present in the cart. It's ideal for bundling related items and charging additional fees like packaging, handling, or service charges.

For example, you can create a rule that adds a packaging fee when a Belt and a Cap are purchased together. The fee won’t apply if only one of the products is in the cart, ensuring that extra charges are applied only in targeted scenarios.

This setup works well for stores offering combo deals, product bundles, or requiring special handling when multiple items are ordered together.

Example Use Cases


Apply a $50 packaging fee when Belt + Cap are both in the cart

Goal: Apply the $50 packaging fee only when both the Belt and Cap are in the cart.

  1. Go to Extra Fees > Add New Fee Rule
  2. Set a fee label: Combo Packaging Fee

    Set fee amount: Fixed – $50

    In Conditional Rules, choose:

    • Product SKU or ID = Belt
    • AND Product SKU or ID = Cap
  3. Save and test it by adding both products to the cart


Apply a $100 handling fee when buying 5 or more accessory items

Goal: Add a $100 handling fee when more than 5 products are in the cart from the accessories categories.

  1. Go to Extra Fees > Add New Fee Rule
  2. Set label: Handling gee

    Amount: $100

    Add two product-based rules:

    • Categories = Accessories
    • Product's quantity > 5
  3. Set the condition type to AND, then save
