9. Recycle

You may have seen the Seinfeld episode where Kramer plans to drive thousands of empty cans and bottles to Michigan to take advantage of the state’s 10-cent bottle deposit return. While you don’t want to pull that stunt in real life – it’s illegal, as one man discovered – you can return your empties for cash in certain states, including New York, California, and Oregon.

Crushed beer cans aren’t the only thing you can get paid to recycle. You can earn store rewards by returning empty ink cartridges to Staples and Office Depot. Old car batteries and scrap metal can also be sold for cash, and retailers like Amazon, Target, and Apple may offer gift cards in exchange for your old gadgets.
