I sent for a $40 rebate with Asus for a blu-ray drive on Dec 4 2014,on Dec 19 2014 I got a "Reminder" that they did not receive required documents,I keep copies of everything and resent on Dec 20-2014 with certified mail.I am waiting to see what they will do next,I advise anybody that if you buy anything with rebate from Asus,you must keep copies of the documents or they will deny your rebate,I sent many rebates, from other companies,all to the same address at El Paso, Texas and they all received except ASUS.Beware of this company.
