At Blue Sky expires the 25th http://www.blueskycycling.com/produc...-w-Adapter.htm
Those expiration dates get extended all the time. The $90 deal is for silver, front, IS mount with no adapter. A good deal if that's what you're looking for, but the more popular options jump to 120/130. IMO the SLX is a better deal right now.
