Right now I’d guess about 20 are full of stuff and being used, about 10-15 are nested in storage, the rest, some have broken and I tossed them, some I’ve given away to people.
I should also add we tend to use red and green for christmas and their are other colors so that can help.
last time I moved I bought a bunch of suitcases on wheels from the op shop (goodwill type shop) worked a treat and they went back when I was finished with then
I always got empty boxes from Kinko’s or other similar copy shops. It’s harder to get them from Fedex now because they flatten and toss them immediately. They are a good size, and uniform.
Hint: Get extra lids. Put one lid on the bottom of the box for extra strength.
