Using Expedia to book trip, how is their rewards programs?

[JohnDaleswife]

Anyone use Expedia to book their trips? I am wondering if you could get more bang for your buck with their rewards program vs. Orbitz. I like Orbitz really well, but just got to wondering about Expedia. I don't think that Travelocity or Hotels.com rewards programs are all that great.

Does Expedia offer additional % off as well?
