You will need to "Like" them, under Being a Good Girlfriend tab, at the bottom is a link to request a trial of it. The link will take you to P&G Brand saver page to which you will need to sign in or register (its free). If you've requested a sample in the past you won't be able to get this one. You can only request their samples every 90 days or so.
