I use the "authorized" for rebate considerations. I just don't deal with the places that stand a high chance of being a scam.
Well as you said.....www.newegg.com is NOT a scam operation, but some on the list are. With that thought in mind NewEgg maintains that they are a authorized canon outlet, and they directly link to the rebate form at canon from their product order page.
I have asked both Canon and Newegg to clear this up for me. I am considering buying the the 20d camera (as a backup) and a 50mm f/1.4 from NewEgg and I don't want to miss the rebates I would get.
