I just got "rejected" on my $75 "rebate". Reason? None! Gave up trying to call after being on hold for 30 minutes, will try again on Monday. I sent in one barcode from the box, the one that said "UPC", to keep the letter weight under one ounce. Which one did they want? All of them? The rebate company is TCA Fulfillment Services, Inc and they seem to handle most rebates. They recommend registering with them. When I did, a rebate for a DVD burner was approved within minutes, even though I sent it in 4 weeks ago! I bought the Senergy714 from NewEgg, the DVD burner from VideoGuys.
P.S. I finally got through, the phone phlunky said it was a "mistake" and that my rebate will be mailed March 31st. We'll see.
