I hope this timeline helps:
According to the Lite-On rebate line at 1-866-205-3231, my info was entered in their computer on Sept. 16. On Oct. 28 I received my check.
According to allisolm her info was entered into their computer on Sept. 24, 8 days later then me, so I figure she should get her rebate on or about Nov 5. To the best of my knowledge she hasn't received it yet.
If your rebate was submitted later then hers you will probably be stuck waiting at least another week. And if Lite-On received it before my info was entered, and you have yet to receive your check, I would be angry. I would politly complain to both Lite-On and Best Buy if you feel it's worth your time. Your other choice is to wait about 2 more weeks. From the day I mailed it in to the day I received my check was just shy of 11 weeks.
