Sending a Share A Box invite is easy! Once you've logged in, click the purple icon located in the upper right hand portion of the screen. From there, click "Share A Box" in the drop down. This page will show you how many invites you have to give, and of course, the invite form itself. Simply fill out the form with the recipient's email address, name, and a special message (including a message is optional).
Click "Send Invite," and your invite will be on its way!
