I'm advertising, and have some other ideas that I've found from this site. I'm wondering at what point is it worth it to buy metals to then resell? I've seen another post on here about asking what stuff weighs. Knowing the weigh is important, and what it is worth is important too. I'm thinking of my local goodwill, thrift store, or garage sale. If I buy enough at the GW I can pay .89 per lb. I could see where it would be worth it for brass or copper, and maybe worthless for anything else. I did do well from an old sears table saw I got with a bandsaw from Craigslist for 20 bucks. I got 25 for junking the table saw, and eventually sold the bandsaw for 150. I'm looking to do some farm cleanouts maybe, and I'd like to offer some money in hopes to make several bucks?
