You can register one or several shipping addresses in advance, in order to save time when you back a project.
First, access your Settings page by clicking on your name / username on the top right corner. This will display a menu: click on the Settings link. From this section, click on the Delivery addresses tab.
If you have already registered addresses, they will be listed with icons to edit or delete them.
Below, you will find the form to add an address. Fill in the fields and click on the Add button.
Saved addresses can be used later when you contribute to a project or on an existing contribution. In the latter case, go to the section My contributions and click on the pencil shaped icon next to the relevant project (option Edit address and preferences). On this page, you will find a form allowing you to use a saved address. (See How to associate my postal address to my support to an Ulule project?)
