@klloll and @B-Olivier sorry - didn't saw your comments until today.
Still an issue?

Hi!
Is there an update to the script?
I applied this to my latest woocommerce site and it notified me that "woocommerce_get_price" has been deprecated and changed to "woocommerce_product_get_price".

And the script didn't seem to take effect even after I changed the syntax.
It would be nice if we can have an update :)
