Any point in keeping packaging for open figures?

We have a bunch of Skylanders from when my daughter was younger, and I'm a box hoarder so I still have most of the packaging. All of the figures are open since she used to play with them.

Is there any point in keeping the open packages? Does it add anything to the value if i decide to try and sell them some day? They take up a bunch of room so I'm debating tossing them.
