It's your birthday - treat yourself! At a handful of places, like Cracker Barrel or Denny's, you can tell the server it's your birthday and you'll get something for free, but if you're looking for discounts at Ace Hardware or Applebee's, your best bet is to sign up online, print the coupon when it arrives in your inbox on your birthday and then present it on your one glorified day of awesomeness each year.
