Posting directly to Facebook is very simple. Be sure you're logged into your account with an active Hallmark eCard subscription, otherwise, the 'Share on Facebook' button will not be visible. Once you're on the eCard 'Quicklook View' there is a 'Share on Facebook' link available.
Another easy way of posting an eCard directly to Facebook is on the Personalization Page. Just click the Share eCard on Facebook link.
Privacy options are available as is the Cancel, and Post to Facebook button. Please know, when composing your personal message, this will post to Facebook and not within the eCard itself.
