I use Hotwire for hotel rooms and have been quite pleased with it. Can almost always get a three or four star hotel for $60-$80. That's impossible on any other site other than Priceline.

I try Priceline on occasion, but my price calibration is not matched to their pricing in many cases. I think I know the market, but cannot get the room at the typical price. They force you to wait 24 hours to attempt again.........so...........go pound sand.........
