How can I get a camera from canon for free ?
with out having to take surveys or having to buy anything
It is not possible to get a camera from canon for free without having to take surveys or having to buy anything. It only comes free when you buy particular items which are on discount. Therefore, one has to ensure that the item has been listed.
Not everything in the world is free. Unless you want to go to jail, there isn't a way to get it for free. Discount, maybe, but not free.
