If you are an American Express cardmember and have not visited "Going Once"  you are missing out.
There are nine declining-price packages, offered one per weekday from
10/3 - 10/13. Each day, a declining-price travel package will go on
sale at 12PM ET. Starting at 12:20PM ET, the package price will drop
every twenty minutes until 8PM ET or until all the packages are sold.

You never know how much the price is going to drop. Which ads a cool gaming aspect for those who have the time.

Lets give it up to the design team - as they did a great job making the destinations paramount in their GUI.
