Out of Stock alert at checkout page

hello, how can I add out of stock warning into checkout page? This warning is in shopping cart but when I skip it I need it in checkout page as well.

Can you help? Thank you very much.

better, either let 'em checkout, if they ignore the Cart Warning, or then not!
Everything else makes not much sense.

I need let them checkout, but they need know it is out off stock so will be delivered with delay.

Is there an easy option to notify or send alert to the same customer when the stock availability is back?

1 - As long as the order status has not been completed, how can it be distinguished if the customer must be really alerted since the order status has not been set to completed due to an out-of-stock event compared to other order statuses events other than those who might already be completed? Since Opencart does not have any categorical order statuses reports other than a text area window in the admin orders where merchants can add their reason related to the order, although, without a select option.

2 - What if the email message can't be sent to the customer's email? What would be the second option if the customer cannot be notified this way?

3 - Since Opencart does not store any orders categorically with their products by default, how can it be distinguished if the stock level to where the customer ordered the product is the true match to where the product was ordered from the store under the right category page since Opencart allows to copy the same and other products over different categories?

4 - If the product is no longer offered from the store period but the time period where the customer did ordered the product was one of the last or the last one on stock, how can we notify the customer by then?
