It appears to be very difficult to take advantage on the falling ISK right now. The foreign currency desk at my bank told me on Friday that they are buying ISK's at around 300/dollar, but selling ISK's at around 110/dollar.
Here is a link to VISA USA, and they are converting ISK's at 111/dollar for credit cards, as of Saturday, October 11.
