To include/exclude referral coupons on products/categories, go to WordPress Dashboard > EchoRewards > Referral Settings
Then, look for the “Include products” or “Include categories” options if you want to include something to your referral coupons.
If you want to exclude something, look for the “Exclude products” or “Exclude categories” options.
Once you’ve found it, select the names and click on “Save changes.”
The procedure for “Excluding products” and “Excluding categories” is the same as described above.
