Go hunting or foraging for food. You may need to invest in gear and permits, but if you already have these, this is an inexpensive way to get your own food. If you're ethically against the killing of animals, it's pretty easy to forage for food, depending on where you live. Just make sure to forage only for food whose origin and properties you are sure of. Getting sick or poisoned is never any fun.
If there’s a plasma donation center in your area, you might be able to make anywhere from $25 to $50, and odds are, you’ll get paid today. Call ahead and ask, of course, but these days, many donation centers are giving money cards (similar to a debit card). Generally, it takes about 30 minutes to donate your plasma, but a first visit may take longer — up to two hours — since you’ll be filling out paperwork and taking a physical. And while it’s not a ton of money, many donors are able to sell plasma twice a week.
If you’re serious about making money selling things online, it’s pretty much impossible to not recommend Shopify. The platform gives you everything you need to get your online store up and running in less than a day including a custom domain, beautiful templates (so you don’t need design skills), secure payment options, and they can even take care of marketing and shipping for you. Whether you’re promoting your own products, designs, or curating other products for people in your niche, Shopify is the best option for powering your online store.
If you don’t live in a bottle deposit state, you can still cash in on recyclables by selling scrap metal. You may not have enough soda or beer cans lying around to make this worthwhile — and steel prices are so low right now, it’s not really worth the bother to go collecting them. But if you do have a lot of aluminum cans on hand, or if you have any scrap metal with copper in it, find a local recycling center and see what you’ll get (prices vary wildly by market). Still, unless you have a lot of copper pipes lying around the garage, or bags and bags and bags of old soda cans, realistically, we’re probably talking about getting $5 to $20 back.
