The old coffee cans in my garage. Saved by my grandpa, my dad, and me. More cans with stuff from garage and estate sales. LOTS of cans. No driving, no wasted gas, no digging in my wallet, no surfing the net looking for stuff, no shipping costs. Downside is imperfect inventory control and cataloging -- dump a can into a beverage flat and sort through it. At least it is segregated into big bolts, small bolts, metric bolts, stove bolts, machine screws, etc. I feel really dumb buying a few bolts on the net or driving across town for a couple machine screws, but I did just that yesterday for four metric flat socket head bolts, I didn't have the size I needed in stock and no substitutes were allowed... 8^)
