Let's say you offered your client a Promo Code on their next purchase. You can quickly change the notes-help-text displayed on your Wishlist cart to read as 'Promo Code' instead.
You'll first want to navigate to your 'Plugins' located on your Dashboard and click on 'Settings' listed beneath the 'Goodshuffle Wishlist' Plugin.
Once you're on the Settings page, you can scroll down to the 'Notes Help Text' field and change the text to 'Promo Code'.
Once you save these changes, you can navigate to your Wishlist Cart to see the updated note text.
When your client submits their Wishlist with a Promo Code, you'll find it listed in the 'Notes' section of the project within 'External Notes'.
