I recently stumbled across the above site. It is a great site that allows you trade in frequent flier points for money. You cannot trade them for cash, but you for gift certificates. The good thing is that they have partnerships with a variety of vendors including Home Depot, Lowes and Sears and so you can redeem your miles for gift certificates from these stores and many others.
This is a great site especially since it has gotten harder and harder to redeem miles. This is a great way to take advantage of accrued miles.
