read the terms carefully.  with promotional offers, if you do anything "bad", the promotion is terminated and you immediately revert to either your normal rate or a penalty rate. "bad" includes things like: making a late payment, going over your limit, paying less than the minimum payment, etc. i wouldn't sweat the potential credit score impacts. these promotions are pretty much the best deals that you can get for an unsecured loan.
