If you have more than one gift list on your MyRegistry.com account, you can easily remove one of them using the following instructions:
To remove your registry you no longer want, first, select the registry from your toggle menu located at the upper right corner. Be sure to select the registry gift list that you desire to remove to avoid removing the one you actually want to keep.
Simply go to SETTINGS, and select Profile & Shipping Info. Underneath your Details section, you will see the option to Deactivate MyRegistry Account. You will then be directed to choose your reason for deactivation. Once you have selected your choice click Delete Permanently then DELETE (TYPE) OF REGISTRY.
A deactivation link will be sent to the email address associated with your account. Click through the link and your gift list will be removed from your account. This process will only remove the gift list that you are logged into at that time; the others will remain active.
