Paying Bills With Unwanted Gift Cards?

GiftCards.com recently launched a new service where people can trade in their unwanted gift cards and pay bills (electric bill, cell phone bill, car payment) with the cash they get. The first question that comes to mind for me is, is this something people actually want? Why wouldn’t someone just get cash for their unwanted gift card on any number of the available sites that offer this service and use the cash for whatever they want?
