Do you keep the same movie twice?

[Rz_Samurai]

I was wondering on what you guys do. Lets say to give example you ordered a steelbook of true grit, but you have a regular blu ray with slip cover of the same movie. Do you actually keep the regular blu of the movie or do you sell it to make extra cash or trade it in at a moviestop? i ask because i have had a couple of blus already and i just finally came across on buying the steelbook versions, and to me i think its best to just go ahead and sell of your regular editions to get that extra money to get another movie. What do you guys think?
