If you sell physical products, you can offer free shipping on all products by creating a free shipping rate. Alternatively, you can create a free shipping discount. If you're on the Commerce Advanced plan, you can set the free shipping discount to apply automatically at checkout.
For shipping basics, visit Setting up shipping rates.
Note: It isn't possible to set per-product shipping rates, so the "Free Shipping" option will be available to any customer checking out. To limit free shipping, create a discount and share the promo code with select customers.
Set a free shipping rate
You can offer free shipping by using the Flat Rate shipping option. Enter "Free Shipping" as the Option Name, then set the Per Order Fee and the Fee Per Item to $0.00.
Tip: To offer free shipping to local customers only, visit Creating shipping zones.
Offer a free shipping discount
Create a free shipping discount to remove shipping costs for all orders, or for orders with a subtotal equal to or over a certain price. Free shipping can include all shipping options, or be limited to a specific shipping option.
You can create a promo code that customers can use to claim their free shipping, or, if you're on the Commerce Advanced plan, create an automatic discount that applies at checkout when the conditions are met.
