I don’t have room to store all the boxes. Honestly, I don't think having boxes for items results in easier or more profitable sales when/if you do that. I save boxes for the more expensive items (mostly engines) and pitch the rest. It’s sort of a gamble, I guess.
I wouldn’t get hung up over saving boxes, though. If you have the room, fine; if not, let them go. I sell stuff on Ebay and don’t notice any reluctance to purchase my offerings without boxes if the price is right.
