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

I live in an apartment, and don't have much space to keep the original boxes.  I sold my last pair of speakers and subwoofer on eBay, but for local pickup only.   I don't think it's worth it for me to rent storage space just to store the boxes.

Agree with all of the above

If you get rid of the boxes you are possibly restricted to local buyers, which might be OK

Original boxes are all about getting maximum protection for shipping. Nothing hand made can mold to the specific equipment quite as well. Hence the value of it if you plan on selling it down the road.

Having the original box and packing materials from my vantage point are important from selling or buying standpoints. I keep all of mine, but I have room to do so. I don’t generally buy used gear but if I do  and the seller doesn’t have the originals I pass. What someone thinks suffices for internal packaging vs what the manufacturer does to limit possible damage can be 2 very different things

I tend keep the boxes for gear that would require freight/pallet shipping.
