Earn double points on Priority Club Rewards partner activity from July 1- Aug 31, 2010.
For example, you earn 6,000 points for signing up for Netflix- better than the 1,500 Delta miles you get for the same activity.
Also, 30,000 for DirecTV (though to be honest I didn't even realize that still existed.)
