I am running out of room in my storage with all the empty boxes. Is it worth just dumping them? Is there any value to just the box?
Depends on what boxes you mean, the inner or outer boxes. If you mean the outer boxes/cases then probably not but if you really want to keep them just flat pack them. If they're the outers of an especially limited production then again, sure keep them.
If we talking about the inner boxes, i.e. the boxes the statue or figure etc came in then again it comes down to the rarity of the figure itself.
As I general rule I would say keep the inner boxes but ditch the outers.
Hope this helps
i fill up boxes.
Real well.
