I'm using the shipping fields for another purpose as intended by shopify (thanks to the language files).
the only thing is now I need to hide this section from the checkout and control you data page. I checked that the shipping is always the same as the billing address so the only thing I need to hide the div block with css. So it is there but not visible.
Extra info: I'm using the supply theme from shoppify
I think there is a reason all these people asking if there is a way to remove "Shipping address" don't have shopify accounts anymore.
Shopify Store: Is there a way to make my store more simple?
Shopify Customer: Why do I need to put in a shipping address for a local pick up?
