Last Christmas prices dropped as Canon dumped surplus inventory to shore up sales due to a poor quarter and to make sales for 2011 look good.
It was discussed back then, that prices would go back up to MSRP, and they have. Canon is also now requiring resellers to sell at MSRP, unless its a Canon authorized sale.
You might find something for less on ebay, but goods purchased at auction are specifically excluded from the Canon Warranty.
