Create a flat rate shipping option for no cost.
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. Both options can be an effective way to increase sales, even if you factor the cost of shipping into the product price. If you're on either the Commerce Advanced or Premium plans, 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.
Offer a free flat-rate option
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 weight-dependent option
You can assign different shipping costs to product weight ranges with depending-on-weight shipping. You can use this to charge more for heavier items, and also to offer free shipping on light orders. To create a free weight-dependent option, make the cost of one of your weight ranges $0.00. Ensure you've added weights to all your products so that shipping is calculated accurately at checkout.
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. The order minimum must be met after any other discounts apply to the order.
You can create a promo code that customers can use to claim their free shipping, or, if you're on the Commerce Advanced or Premium plan, create an automatic discount that applies at checkout when the conditions are met.
