If you're frugal, TV-obsessed, and in a relationship (a winning combination if there ever was one), you might want to check out ABC.com's free Valentine's Day e-cards. You can use your favorite characters from Grey's Anatomy, Ugly Betty, and Lost to express your love for that special someone. Tell your significant other that you're McDreamin' of them, send a post-it note from Henry Grubstick, or impart a creepy--but loving--message from Benjamin Linus. My only complaint is that more ABC shows, like Pushing Daisies and Dirty Sexy Money, weren't included. Who wouldn't want a valentine from Olive Snook or Clark the driver?
