Offline Monetizing W/O CPA Stuff?

I don't know crap about IM, CPA landing pages and stuff mean nothing to me, I signed up for CPA lead once and never even signed into my account after that. I'd like to to learn about everything but right now I'm really broke and need a little bit of cash. Any tips on things I can do door-to-door or just on the street? I'm not able to make an investment but I was thinking about buying those coupon books in bulk and selling them door-to-door. Anyways, thanks!
