Hi at the mega marts at celadon, goldenrod etc .. theres in the entrance a guy that buy itens like fresh waters...(...)

 

eventually get there and see by yourself, about pokémons is not possible to do that because you need a price fixed for every pokémon and is not what we have.

 

eventually you can exchange to some items at item recycler at johto check it out.
