I just bought my first dSLR, a 5D from Amazon, and it arrived this morning. Then I saw this post. Arrg! I wrote to Amazon to ask how they would handle this and they said that they are unaware of any rebate, but if one does appear, my best bet is to go try to go through Canon since it would be a manufacturer's rebate. Failing that, she said I would have to return the camera for a full refund, and reorder.
If we do get a rebate, I plan to contact Canon as advised. If I have no luck there, I'll contact Amazon again and see if an "on the books" rebate changes anything. I really don't want to have to send it back and rebuy... it would be silly! Has anyone had any luck with Amazon in a similar situation?
On a side note, this seems like a great forum. I'm sure I'll learn a lot by lurking here.
