Update: As of July 1, 2010, the rebates on the 1Ds Mark III and 5D Mark II are over but other rebates are continuing until end of July.
Canon Canada has some amazing instant rebates going on right now, but keep in mind, they are only until the end of June! While there is a chance that Canon will extend the rebates, at the moment June 30th, 2010 is the deadline... so do you really want to take a chance and not take advantage?! Here is a complete list of the EOS body rebates...
EOS-1Ds Mark III - $1000 (ended July 1st)
EOS-1D Mark IV - $300
EOS-5D Mark II - $500 (ended July 1st)
EOS-7D - $150
EOS-50D - $100
EOS Rebel T1i - $100
EOS Rebel XSi - $30
EOS Rebel XS - $30
There are also rebates on a whole slew of Canon lenses, but the list is a little too long to put in here, so I am just going to link to a PDF File with all the rebates detailed, including the bodies as well. We anticipate that the $500 rebate on the 5D Mark II will likely be one of the most popular, and we have lots of bodies in stock!
Secondly, as far as CPS orders, if you have not signed up under the new program yet, any purchases that you'd like to make with your old CPS number will need to be submitted to Canon by June 30th. Don't wait until the last minute!
