Haha! I use to keep the boxes for everything at one time, just in case I ever had to return something. Often the boxes outlived the equipment!
And you never know when you might need a box to put something in or post something. lol!
A cockroach plague ten years back soon put an end to my box collection. They went for anything made of cardboard. So all of the boxes went to the dump and I never missed them. Haven't seen a roach since!
