spending way too much time on Facebook today, but here’s another potentially sweet deal:  “Like” CVS on Facebook and register your card and email.  If 250,000 people “like” them by Feburary 11, they’ll send out (using the email given) a 20% shoppers pass good on February 14, 2011.  The more people “like” them, the higher the discount, potentially topping off at 25%.
