Office Max has a new add out today for a 100 pack (spindle) of HP DVD+R 8X for 29.99 after rebate. The regular price is 79.99 with an INSTANT rebate of 45.00 and a mail in for 5.00 more. So without the mail-in they are just 34.99. Does anyone know who makes these and if they are any good? I have not looked at the packages so I have no idea where they are made.
