I pre-registered online for my $20 rebate for the 100mm f/2.8 and sent everything in I was supposed to. I get a card in the mail the other day that says that an invalid UPC was submitted, and I need to resubmit within a couple of weeks to still get the rebate.
First of all, to pre-qualify online, you have to submit the UPC # from the box. Then, it is accepted and recognized as the lens you have. So, if I sent them the SAME UPC from the box that I pre-qualified online with, and it accepted as the Canon 100mm f/2.8 macro lens, how can that be invalid?
I did send them all three bar codes on the box, although they weren't all cut on the same piece. Are they just trying to dick me around or what?

....and i got my tamron rebate in little over a week as well as a 6-year warranty
