Why Rates Show Double Amounts During Checkout
You'll understand why combined rates appear and how to manage multiple shipping profiles effectively.
When customers add products from different shipping profiles to their cart, Shopify automatically combines the separate rates into a single total. This creates the appearance of "double" shipping costs.
How Combined Shipping Rates Work
Shopify combines shipping rates when:
- Products come from multiple shipping profiles
- Items ship from different locations within profiles
- Each profile has its own rate configuration
The system calculates separate rates for each profile's products, then displays the combined total at checkout.
Identify the Root Cause
Follow these steps to diagnose combined shipping rates:
- Check your shipping profiles
- Go to Settings > Shipping and delivery
- Look for multiple active profiles
- Review rate configurations in each profile
- Test with mixed cart items
- Add products from different profiles to cart
- Check the shipping rate calculation
- Verify the combined total
Solutions to Manage Combined Rates
