Hi @Glojewelry. Thanks for being part of GoDaddy Community! There isn't a way to do either of these things currently. Coupons can only be limited by a single category if you choose that option. However, they will apply to any subcategories under the category you choose. The only way I could see getting around that would be to create similar coupons for other categories.
