Group Gifting allows multiple people to chip-in toward an item listed in your registry.
When you first create your registry, all items over $100 have Group Gifting enabled by default. (From a logged-in state, view your Registry Settings to make changes to the group gifting feature.)
When your friends and family chip in on an item in the Target Registry, you will receive a Target eGiftCard -- and not the physical gift itself. You can apply the eGiftCard toward the purchase of the selected item -- or ANY item -- from Target (in-store or online).
