I followed the instructions given by Privateyez, but I didn't order contacts this time. The rebate form still comes up when you click the link, but you have to either click "On or before December 31, 2010" or "on or after January 1, 2011." So I guess something must have changed on the first of this year. I clicked on "on or after January 1, 2011" and still got a rebate form opening up, so I guess the offer still stands.
