Hi there!

We just bought the pre-order plugin, everything works fine, except one thing: we would like to display some comment/message on checkout page, that the selected product isn't on stock (it's pre-ordered). Is there a way to do that (on frontend and admin page)? Is there a way to send that message with email too?

Thanks in advance!

Don't you want to develop this remarkable plugin to display some text automatically on checkout page and on order email?

So if I have 5 product in cart and one of them is pre-ordered then I have some text under the exact product.

This will be a huge step. Product custom field is just a safe solution.

Thanks Jerome
(btw Hikashop is awesome)
