I bought the Office:Mac 2004 Student edition from Amazon a couple of weeks ago becuse they had the $20 rebate bringing the price to $109 shipped. I have finally gotten around to filling out the rebate forms and I have one problem: I cannot find the UPC anywhere on the packaging. Does anyone happen to know where to find the UPC? The only thing I see on the box is the MS certificate of authenticity. Thanks for the help!
