I was looking around on a Canadian Camera store called Camera Canada and I found this Mail in Rebate. Link Now they are the L lens', battery grips, flashes and a few body's. I don't know if its a Canada only thing but maybe some of you better informed Canon guys will know. It looks legit enough and being able to get 500$ back on 2 lens' is a sweet freakin deal. Here is some obligations on the page I found the deal on. 1. This promotion is not valid at the following retailers: Future Shop, Best Buy, Costco, Sam's Club, Wal-Mart or Canon E-Store. 2. You must purchase eligible products at the same time, as evidenced on the same invoice to be eligible for the mail-in-rebate. Failure to do so will result in the subsequent submission(s) being denied.
