Hertz: Economy car rentals/day ... with a catch

For Florida residents, Hertz offers its Drive-Out Economy Car Rentals for $5 per day via rate code "1WAY" and promotional coupon code "102071". (Weekly rates start at $19.99.) What's the catch? You'll be picking the car up from any of seven Florida airport locations and repositioning it within one of 36 locations. Those locations aren't next door: Destinations include Boston, Newark, Detroit, and even Phoenix, AZ. Note that you can get a free upgrade to a full-size car via the above codes through June 30.
