I'm in the process of getting my store up and running. I want all items to have free shipping to everywhere with no conditions. When I was doing a test run a shipping rate labeled as "flat rate" still keeps showing up and I don't know why. Why is this happening and how can I fix it? I just want to make sure that all my customers all over the world get free shipping as advertised.
Go to Settings > Shipping > Rates at checkout section > Manage rates
Then add shipping rates for the zones you serve. Example Domestic and Rest of World.
