You can buy the red storage boxes at Rural King, HF, Menards, and perhaps many other places. However, Menards gives theirs away after rebate, limt 10. Menards has the rebates on these items every few months. I've got about 50 of them. They come in a larger size too, not free. The expensive part are the mounting brackets. I made my own. You could even stack them, make a shelf, use light weight angle iron, the kind used to hang garage doors with.
I also like the stanley organizers. I carry them in my truck. Nice to have bolts, screws, and electrical items when I'm away from home.
There is no one size that fits all. I have everything from 5 gallon buckets, coffee cans, cut the top off oil bottles, metal drawers, plastic drawer organizers, even used the drawers form an old water bed to store larger things in. You will never have enough storage. They all seem to fill up to max capacity.
