Nice piece of code. Thank you.

very helpful. thanks.

Great collection, thank you for share!

How can i put the username of the costumer in the notice?

highly appreciated, thank you.

how to add transitions of the notices, so that they fade out after some time!!

Great collection covering the options. Many thanks!

Thanks for these snippets. With the help from following link - anything is possible in Checkout page
WooCommerce Visual Hook Guide: Checkout Page

thanks for this. I want to change the success/failure notice for applying a coupon on my cart page.

would this code in my child theme overwrite the default notice text?

Thank you for this code. Does the woocommerce_review_order_before_payment example mean to imply that one will not see error messages unless placed as described?

tks you
