i have appleCare+ too..

have you read the fine print?
Apple hardware coverage
AppleCare+provides repair or replacement coverage, both parts and labor, from Apple-authorized technicians. Service coverage includes the following:
Your iPhone
Battery
Included earphones and accessories
Coverage for up to
two incidents of accidental damage from handling, each subject to a
$49 service fee plus applicable tax.
i doubt that you will rush to a genius bar for a small blemish or a light dent on the iPhone, use one of your "TWO" lifelines and pay $49 plus service tax.
