If you aren't already inclined to scrounge for "junk" then become friends with someone who is 
		
		
	
	
Know anybody who collects anything and everything?? Usually they're outgoing and frieindly, so make friends. hehehehe
You might learn a "skill". I walk my dog and make note of all the interesting stuff set out by dumpsters, then drive back to get it. OR drive him around town and he can look while I concentrate on the road.
My father and law collects EVERYTHING he can from dumpsters and roadsides and wherever. Some of the things truely are JUNK, but I don't care, it's his yard he puts them in. I got 4 big posts from him and a bunch of 2x4's, plus some tin, all for free for my new chicken coop. Because I hang out with him is where I met Bob of "Rusty Acres" the scrap yard where I managed to get lots of fence and coop supplies on the cheap. Not only that I used him (my father in law) for labor -  I made him carry 80lb bags of Quickcrete for me - so far the price of my coop has been $6 and some change for the concrete to set the posts, plus about $10 for more nails and screws.
I also have had a pallet that I "stole" from his yard for a back gate on my deck for about 2 years. I'm hoping to "upgrade" to a chainlink one so my doggy can see out better, but the pallet has served us well and the price was right. He also gets free 5 and 3 gal plastic food grade buckets, with lids, from the 
Wal-Mart bakery. I love buckets! I have no idea where he turned up a plastic barrel, but that's what I compost in. People always charge for them on Craiglist, but mine was free from my father in law.
