Storage boxes. Can I discard high end shipping boxes, and still sell in the future?

People value the original box more than it's worth from what I've seen.  You take a BIG hit without it.

I used to store all mine in the attic, but now I keep everything locked away in an empty office at my job. A fringe benefit of being the Building Operations Manager.

you must have a lot of equipment if you need to have a storage unit for just the boxes. Don't the boxes have a lot of air in them, can't you collapse them?

Possibly cut them at the seams and flatten them for storage. Repurchase packing material when you sell.

If I flatten the boxes and discard the original foam, will the resailability be as adversely affected? In thebfuture I can ship the equipment in the original boxes, but with new bubble wrap or other internal material.
