I've noticed few times people wondering if one or another website/store is an authorized Canon Dealer.
I've found this file on Canon Website, which pretty much outlines who you can trust and when you should be cautious.
Not sure if this is redundant and was posted before, but figured I'd share:
http://www.usa.canon.com …anonAuthorizedDealers.pdf
(25 pages long PDF document)
Aleness
P.S. I didn't want to attach it in case if Canon updates the file, the link will always be up-to-date.
