There seems to be a bunch of different lots. When you put your information in, the list is populated with a list of increasing prices, depending on whether you want to valet park or self park, outdoor or indoor, etc.

For instance, when I put in my information on when I want to fly out and return, I got a list of these lots:

1. Fast Airport Parking
2. Fly and Save
3. EZ Park Fly
4. La Quinta Inn & Suites
5. Park and Jet
6. Radisson

When I did an internet search of Fly and Save, I only got back a reservation site.

This reservation site seems to have even more lots. Seems like a kayak.com for airport parking to me. You don't have to make an online reservation, but it's a nice feature to be able to scope out what the going prices are.
