This article covers additional adjustments to the Free Shipping section of the Shipping tab of the Settings feature after you've completed your initial configuration.
To offer Free Shipping in any capacity, make sure the Active toggle is on.
You can offer free shipping on all orders by selecting the Free shipping on all orders check box (if you do, you can't offer price-based or weight-based rates). Enter a Delivery Estimate value to display the number of days a customer can expect to wait to receive the shipment. (This information is visible to your customer.)
If you only want to offer free shipping on orders that cost a certain amount, make sure the Free shipping on all orders box is unchecked and enter the price value of your choice in the Free shipping on orders over field.
When you're finished setting up your Free Shipping method, Click the Save button at the top left of the Shipping Page.
