Abstract: Techniques are described to share items from a favorites list. In an implementation, a list entry for a favorites list may be associated with content from a third party source by a first user. The favorites list may be presented in a webpage to display the list entry and the associated content to another user. A control operable to share the list entry with the other user may be exposed with the list entry. Responsive to operation of the control, the content and/or related data may be obtained from the third party source and data may be stored to associate the list entry including the obtained content with the other user. In at least some embodiments, the control is operable by a single-click to cause the sharing of the list entry.
