When a new store uses Ship Now functionality for the first time, the user will be prompted to read and agree to the terms and conditions of Shippo Merchant Agreement.
Once the user checks the checkbox to accept the said terms and conditions of service and clicks on the "continue" button, the user can use the Ship Now functionality.
