Changing Price Description

Site URL: https://www.khuramanarmstrong.com/endarc-chocolat-store

Hi.  Can someone please advise how to change, or add to, the price description in the store so it includes the default variation description.  In the case below it would include "per [6 pack]" where highlighted in yellow.  Thanks.

Add to Design > Custom CSS

div#thumb-country-feast-set-xs4gg .grid-prices:after {
    content: "per 6 packs";
}

Thanks Tuan.  I was hoping for something more global, including in the product page itself and in the summary blocks.  Also globally across all products, not hard coded per each if possible as we will have many products.  Finally It would be preferable to pick up the description of the default variant, not hard coded.  Any suggestions?  Thanks.

I have no idea. You can try posting on some FB groups
