For Amazon Associates is it better to link to a Blu Ray or DVD?

Link both, I know some people enjoy the Blu Ray, but there are still some that like the regular DVD.

Thanks for the feeback. I like to embed the links into the text of whatever it is I am writing, so I am not sure how to do links for both without dropping the name of the movie twice each time.

Both these products have high competition I believe.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
