I bought ViewSonic LCD monitor at Fry's on 10/14/2006 and mailed the rebate form with all other required document to ViewSonic Rebate in White Bear Lake, MN on 10/16/2006. Checked their web site for rebate status and it always says rebate not found. Called them a few times and they always said it was not the system. It's been 8 weeks and it is still in the system as they claimed it should be. I called them on 12/4/2006 and they said it might be lost in the mail and asked me to mail the form to them again and wait another 8 weeks for processing!
Never trust the ViewSonic Rebate. I am filing complains on BBB.
