This site makes the organization of affinity programs (flier miles, points, purchases etc) a breeze. The ability to determine whne your points expire permit you to plan your travel or purchases.
Award Wallett has also released a card with all your points and accounts on the magnetic strip on the back. When you go to the airport and want this info quickly, voila, it is there.
This site is easy to use, very intuitive and "numero uno".
