People on market place & craigslist will pay you to haul away their old junk refrigerator & bath tubs. If someone pays you $50 to haul away a refrigerator $50 will buy enough potting soil to make a free raised bed. An old TV case & microwave oven both make good flower pots. When my son was 15 years old he advertised on CL he will haul your old TV away for $10 to $15, he had no drivers license so I drove & we picked up 6 or 7 TVs every on Saturday & HE made about $100.
