Whether you use weight based shipping or flat fee shipping, both can also be used with a free shipping discount code which can be automatically applied. Note that this is optional but we highly recommend it since it does improve conversions.
This means you can set a free shipping threshold where a customer needs to spend a minimum amount to unlock free shipping.
For example, customer A can get free shipping if they spend a minimum amount of $50 in the one order.
