Best way to pack a 50lb monitor?

[Burnt]

I have a box for it, how much do big styrofoam blocks cost?

When we shipped my sister's we wrapped it in blankets since the blankets had to get there anyways. Wrapped it up in them on all sides and then packing taped the blankets so it wouldn't come undo. We then packed any empty space in the box with clothes. It worked well.
