You can create a gift list for a family member or friend by adding them to “Friends & Family Gifting.”

Select “Add to Wish List” to view all your wish lists and gift lists. Select the gift list of the friend or family member's name you want to add the item to, and there you go!
Gift lists are shareable by email, Facebook, and Twitter. As these lists can’t be made public, therefore, you need to share it if you want it seen.
