There are plenty of deals to be had on your birthday. Many of these places require proof that you were born on the current day.
Caveat: Many deals have not been confirmed. Please call ahead to confirm a deal, and remove the unverified label to help others in the future. Please also indicate if any purchase is required.
This page is organized according to what your day might look like, morning til late, to maximize the freebies.
