Newbie question alert - what is the CLP program?
Be gentle with me 
From what I understand, it is a program where you can turn in a Canon camera that is out of warranty for a refurbished camera at a 20% discount off the refurbished price. The refurbished camera will have a 6 month warranty rather than the usual 3 month warranty for Canon's refurbs. I have never done it, so this is second hand information.
There are a few caveats: (1) you are limited to the cameras that Canon has available for its CLP program (e.g., if you want a 5D Mark II, it may not be available under the program); (2) people have commented that the cameras may have a fair number of actuations on them (i.e., 17,000); (3) if you are in the USA, you will have to pay tax (i.e., compared to a Canon refurb bought from Adorama, if you are outside NY, with no tax); (4) you must pay shipping (i.e., again, a refurb brought from Adorama may have free shipping).
I have an old A95 that went wonky on me one day. I'm thinking about turning it in to the CLP program for a 5DII or 7D.
