Mom is shocked to learn how babies are evacuated in a hospital emergency. She's not alone.

Sometimes you have to spend money to save money, and people who live a budget-conscious, frugal lifestyle have perfectly mastered how to do it.

In a Reddit post, member jul_on_ice posed the question: "What’s one small upgrade (under $50) that saved you more money than you expected?"

They continued, "Talking about small wins that compounded over time over one thing that made a drastic difference. Frugality is often about not spending but sometimes investments can pay off. Maybe something that made work easier. Made life better. Made you more comfortable. Or something bought once that replaced lots of things you once had to spend on."

Fellow frugal people had lots of money saving hacks to share. These are 35 things that frugal people spent less than $50 on that have saved them lots of money.

"Vacuum sealer. I’m single and most shopping/recipes are four or five meals for me. Often I would have food waste because I no longer wanted the food after the third meal. Now I cook, have the leftovers I want, and vacuum seal the rest in portions. Keeps the food fresh and saves room in my freezer." —mercfan3

"Don’t rent the modem/router combo from Comcast. Just buy your own." —Dove_of_Doves

"A couple of incredibly mundane purchases that I should have made years earlier: having extra sets of measuring spoons (~ $3 per set) makes cooking so much easier; a digital cooking thermometer (~ $15); and a tire inflator that plugs into the car's cigarette lighter ($35) so I can top up the tires at home, rather than trying to find a place with a working air hose. ETA: A french press ($20) and electric kettle ($25). Have used the same french press for more than a decade, and get better tasting coffee without buying filters or K-cups. An electric kettle is surprisingly useful." —Taggart3629

"$9 3-cup rice cooker." —CeleronHubbard

"Popsicle molds. I live in the desert and we eat so many popsicles. Making them myself has saved money and they’re healthier." —Adventurous-Fig-5179

"Dropped cable, kept internet only. Pay for separate Netflix and Disney and all total we save $35 a month over the cable bundle. We did not watch 90% of the channels included. Definite win for us." —GarudaMamie

"Adding an over-the-air antenna. Is a great addition to cutting that “cable tv” cord. It is much easier than you think." —williamtrose367

"We got a renter friendly bidet and it has saved us SO MUCH in toilet paper usage." —Specific_Wait_8006

"We went with cloth diapers when the kids were little it saved us a bunch and kept a bunch of garbage out of the landfill. Once they were potty trained we were able to sell a lot of them." —Responsible-Charge27

"Maybe not a quantifiable dollar amount of a change, but I switched my mindset from “Unitaskers are bad” to “Unitaskers are acceptable if they do the 1 thing better than anything else”. Example: Those plastic pulled pork meat claw things are not better than a fork for the task of shredding meat, but a good mandolin slicer is much faster and probably safer overall than a knife, and rice cookers can cook rice exceptionally well, even if that’s all they do." —Ryutso

"Needles and threads. You can fix anything material with small rips or tears. I’ve extended the life of clothes, bags, and kids stuffed animals by years." —baldbutthairy

"I know this sounds crazy, but realizing I could buy more than one of something (e.g. bath mats, reading glasses, chargers, etc.) I had to really work on changing my thinking around this due to past financial challenges." SomeTangerine1184

"Second hand slow cooker. Money saving meals made from cheap tinned foods: daal, chilli, casserole, soups." —Ambitious_Ad1844

"Anything like this is usually an inexpensive household repair that I waited too long to do. Replacing loose door handles, fixing a leaky faucet, repairing the drip line from my A/C. Little cheap things that just made my life... better." —gogomom

"My aeropress has been a ridiculously good investment. It’s much more portable than a french press. I have it with me now while I’m travelling and I can access a good cup of coffee using the hotel kettle." —mrjasong

"I am a freezie human and nowhere is that more apparent than on airplanes. So I had this 'warm fuzzy' vest for wearing on the plane with a tougher outer fabric and a soft fleecy inner. I paid a seamstress to add an invisible zipper to one of the seams on the inside of the vest and now the gap in between the fleece inner fabric and the tougher outer fabric is what in the 1920s would be called a 'passthrough pocket' or modern hunters might call it a 'game pocket'. But you know what else? It's now my personal item and I wear it on the plane, Scott-e-Vest style, but cheaper. And now because of that, I can fly more budget airlines because I have less luggage-as-in-bags." —heinfamousj

"The jury is still out, but I recently made the switch to rechargeable AA batteries. I'm optimistic this will save me money as I use AAs in my camera flashes and go through a lot of them. It's not a purchase, but rather a process that I think is going to help a lot. I put everything on my 2% cash back credit card and pay it off at the end of the month. Recently, to get a better handle on my daily spending, I decided on what my monthly credit card bill goal should be. Divide that number by 30 and I get my daily spending goal. I then created a spreadsheet and track how much I spend each day and have a column with a running total for over/under. It's motivating to look and see 'Hey, I'm $XXX under budget so far for the month.' The daily goal is high enough to account for things like gas in my truck, haircuts and groceries." —No_Blueberry_8454

"Yearly paper planner. No more missed rendez-vous or deadlines, no more late fees. I tried going digital, but it doesn't work for my ADHD brain. I just snooze the reminders and forget about it. Until it's too late. So I went back to paper, and it's worth the $12-ish per year to me." —Duck__Holliday

"Bought a dead battery Dyson vacuum on Facebook market. Did the Ryobi battery upgrade. Got cheap 8ah Ryobi battery off ebay. Got a cheap Ryobi battery Charger off facebook market. Total all was about $50-60 and it works great." —antsam9

"Dying my hair at my hairdresser rather than at home. No more stains from the home dye. No wrecked towels, clothing or hair." —JoyCrazy

"If you drink a lot of soda or sparkling water, a Soda Stream can help you save. Just the CO2 canisters comes out to about $0.11 for 12 ounces vs paying about $0.50 per can of store bought soda. What gets you are the syrups… that can bring the price up to $0.40 ish per 12 ounces. So to be extra frugal, you could make your own fruit syrups and skip the store-bought stuff. Make a simple syrup (one part sugar, one part water; boil on the stove) and add lemon or lime or orange juice or whatever… I’m sure there are recipes all over the internet. And boom, homemade La Croix. It’s an investment to start, but saves over time." —Drooly_Cat_1103

"Somewhat location dependent but if you are in a dry climate like me and rely on humidifiers running 24/7, buy a cheap water distiller on Amazon (I think mine was like $60 but close enough, you might even find one under 50 if you look/wait for a sale). Distilled water gets pricey, but not using distilled water will junk up your humidifier with minerals which is both a bitch to clean and can eventually cause problems with the function. Save yourself the trouble. Also useful for steam cleaners, mixing your own cleaning sprays from concentrates, misting bottles, etc. At least if you have hard water, anything where you are repeatedly putting a lot through a very small line, distilled is preferred to prevent mineral buildup." —ilanallama85

"I got a Walmart+ membership (got it for $49, it renews at half off the $99 at anniversary). I get free shipping, so when I need something small (like shampoo), I don't need to run to the store. I've used Walmart+ so much more than I ever used Amazon Prime. It costs less, and I find I buy less random crap with Walmart+ than Prime." —sbinjax

"Three inexpensive manual coffee makers: Bialetti Moka Express pot, Bodum French Press, and V60 pour over. Bought all 3, virtually new, at the thrift shop for under 20 total about 5 years ago. The Bialetti makes an espresso-like cup, the Bodum is rich and strong, and the V60 makes a softer, smoother cup of coffee." —zeitness

"Not sure this will ever meaningfully 'pay out' on the investment, but a timer switch for the bathroom fan. I have ADHD and benefit from as many "set it and forget it" items as I can possibly get. Now I can set the fan, have a shower, walk away, and it'll turn itself off after a decent airing-out, and I don't end up walking by the bathroom 4 hours later like 'how long has the fan been on??' Less electricity used, less wear and tear on the fan, less conditioned air lost. Is it more savings than the amount I spent? Probably not for a long time. But it feels better!" —Kitchen-Owl-7323

"A shutoff valve to go above the shower heads in my kids’ bathroom’s so I can limit the flow. We have high water pressure and my kids universally put the faucets at max flow. I used the valves to cut the flow in half. The water pressure is still great but now they use half the water and the hot water now lasts through all six of our showers. I haven’t calculated the savings but I know we are using much less energy in water heating and much less water." —nottherealme1220

"A $30.00 pair of very high quality sharp scissors bought at a sewing machine store 20 years ago freed me forever from paying for haircuts. One YouTube video showed me how to trim & maintain - done. My brother bought a clipper set for $20.00 at the same time and does his own cuts. All that money gets plunked into savings!" —VulcanGreeting

"i switched from some fancy expensive work boots id been wearing to some 18 dollar shoes with 10 dollar insoles i got at walmart. i added the extra insoles on top of the existing ones for extra comfort. this saved me however how much i would have spent for my foot pain that was nearing bad enough to warrant medical attention. these are seriously the most comfortable shoes i have ever owned, i even wear them outside of work, on hikes, just going out on a wet day. over a year in and the extra insoles might need replaced in a few months but the shoes and their original insoles (the ones on bottom) are holding up perfectly. I'm in a better mood at work now too." —cccameronnn
