Scenario: Change shipping price using variable parsed by design during checkout. I need to change the final shipping price using some variables sent by phtml checkout.

Örn.

Shipping method 1: cost 33$

Shipping method 2: cost 23$

Shipping method 3: cost 10$
     special packaging checkbox (y/n) + 10$ (set it as yes for this example)
     assicuration:

Ben sadece tasarım, elle bu onay kutusunu ekledikten ama nihai fiyat artırmak ve sevkiyat bu içeren basit bir etiket eklemek gerekir

toplam olmalı

shipment total                                    20$
