I ended up calling a Canon Rep after four weeks with nothing showing on their site. Within a week, it shows my check is ready to be mailed for $410! Enough to pay for some of the extra costs if canon ups the price from what originally showed. I have another rebate to submit now for $350, I feel a little more comfortable now. I held onto the second rebate, as I did not want two in the system at the same time and have them confuse them if I had to protest something.
I had every I dotted, every t crossed, and still had to call Canon. They might have gotten it anyway, but I am glad this part of the deal is over. I IHATE rebates! I wish Canon wold just run a sell once in a while, even if it is for less money. I know, they don't want to do that, it is more profitable for them to give a $200 rebate then $150 off. Go figure, with all the expenses of them having to hire a company to handle rebates, yet it is still cheaper than that way due to denying rebates, losing rebates, people giving up on rebates or not applying for them. A scam, IMHO!
