From jumper cables to the perfect pillow, essential items can come in any form. Business Insider has compiled a list of 20 useful items you can purchase for $20 or less.
Some of the most useful items are inexpensive.
A recent Reddit thread asked for the most useful items you can buy for under $20.
We picked some of our favorites.
1. Small set of screwdrivers
"With them and the Internet, you'll be surprised how much you can fix stuff, which saves you a lot of money in the long run," writes Reddit user candydaze.
We recommend the Craftsman 8-piece screwdriver set at Sears for $11.69.
2. Fire extinguisher
"If you do need it someday, it will be well worth the 20 bucks," writes DaNinjaKitten.
Try the Kidde FA110 Multipurpose Fire Extinguisher available for $18.98 on Amazon.
3. Carbon monoxide detector
"When my sister and I were younger, the carbon monoxide detector went off in our house. She heard it, I did not. My parents were not home, so she ran up to my room and grabbed me and told me to come outside. We went across the street to our neighbors and they called the fire department for us. My sister saved our lives," writes DoctorCrouchJrWho.
Try this First Alert battery-powered detector for $19.97 at Home Depot.
4. Jumper cables
"When I first moved for college, my car broke down the first week of school in the Wal-Mart parking lot," writes halfwaythere88. "I had to stop a ridiculous amount of people before I found one with jumper cables."
5. Spray bottle
"You can buy them at the dollar store but in my family (and now in my dorm) mine is getting constantly borrowed. It's used for cleaning, ironing, doing hair, and more. The lack of people who have them astounds me!" writes bgaigalas.
The Container Store has a nice bottle for $4.99.
