Which do you prefer? Wrapped or not wrapped?

I know when I send gifts I struggle with the decision to wrap or not wrap. Christmas was easy because well Christmas paper lol. But when I did the rematches for Christmas I just sent the gift via Amazon. For other exchanges I have sent the gift via Amazon but had them "wrap" one of the pieces inside.

I got to wondering about everyone else. Do you care if the gift you receive is wrapped? I know I don't care but do enjoy unwrapping if that is how they come.

What do you do? Do you wrap?
