Hi @Brando1 , I’m not sure if this is what you are looking for but this app Codeboost I use let’s you promote discount codes across your website really well. You can add custom messages including the percentage the discount code will apply on the eligible products, fully customizable.
I like it because I do not have to modify any theme code.
Description from marketplace:
Codeboost will allow you to display badges and messages above eligible products in the collections page, product page and cart page. Additionally you can only show these promotions selectively and privately to specific customers!
Hopefully this helps!
