I have been bidding for 2 weeks to try and get a better Priceline deal for my upcoming trip. I decided to give it one more try. It said bidding $16-18/day for economy (I usually end up with a mid size when I get to the agency) would do the trick, so I said I will try $12. It went through. It's not $8/day like I got in May but it saved me $70 total. That's dinner at BarAcuda!
