There is a promo link roaming around via Adorama's Twitter page. The affiliate link is a code added onto the link for commission sales. Therefore there is a non-affiliate link that should be posted per POTN's rules.
I can't find it searching adorama's twitter page...it doesn't exist there...the only places I can see it are canonrumors.com, and the canonpricewatch link...which both have the affiliate link...
i don't think there's a way to get the deal without an affiliate link
if you can find it, please post it
