How can I change the product save message to display percentage saved?

Hi, does anyone know how to change the product save message to be a % rather than an actual figure?

For example in the below image, to change it from save $2.10 to save X%…

I found the code that i need to amend in the product.grid.item-liquid:

{% capture saved_amount %}{{ product.compare_at_price | minus: product.price | money_without_trailing_zeros }}{% endcapture %}

{{ 'products.general.save_html' | t: saved_amount: saved_amount }}

{% endif %}

Hello! A little math and everything will work out. To minimize your time and mine I’m asking you for access to the themes through my partner account so I can do that right away in your store. I sent you a request for access to the theme of the store greenbottleshop.com

Hi there, do you think you could talk me through it instead? I’m sure you’d be great but have had some bad experiences of giving people access before…

Thanks!
