Product Grid Sale text

Dears,

I’ve spent literally hours with trying to change the “Sale!” text on the badge in the Product Grid as I thought it’s driven by woocommerce. After trying out plenty of code snippets, even modifying the the file itself in the /wp-content/plugins/woocommerce/templates/loop folder (sale-flash.php) I couldn’t achieve the result.

So my assumption is it is driven by the Product Grid.

Can you please help me out on this how I can change the text on the badge?

Thanks in advance.
