Expected result
After applying a promo code and updating the shipping address, the Place order button remains active and submits the order successfully.
Actual result
The Place order button becomes visually enabled but does not respond to clicks — no network request is fired and no toast is shown.

Steps to reproduce
- Add any item to the cart and proceed to checkout.
- Apply the promo code SAVE10 and wait for the total to update.
- Change the shipping country from the dropdown.
- Click the Place order button.
