HOTWIRE was showing $12.95/day hot Rate for my dates, so I tried $10/day at PRICELINE and got it the first time. Probably could have bid less, but I still saved $9 over HOTWIRE. I'm also stoked about getting National, as I may get an upgrade with my Emerald Club membership. Dates: 5/2-5/6/13 Location: Detroit Metro Airport (DTW) Class: Economy Price: $10/day ($61.44 for 4 days after taxes and fees) Company: National
