I looking for a Event to be triggered when a user, via adminhtml or API/SOAP, change prices of a product.
I have been check this, unsuccessfully: https://www.nicksays.co.uk/magento-events-cheat-sheet-1-7/
If the event you are looking for does not exist, think about doing overridden the core, at the time the product is safe. What do you think of this idea?
Any idea is welcome, thank you.
