In my quest to save some $$, I found this website which cut most of my airport parking rate by over 66%! Check it out during this mucho expensive traveling season...

My girlfriend used expedia to get airline ticks, and supposedly expedia gave her two free days of parking near the airport she flew out of. Unsure if this works at all airports etc... But definitely worth a little extra searching while on expedia buying tickets.
