If you’re committed to the frugal life, there are certain things you just can’t afford to do. Unfortunately, it’s hard to avoid falling into all kinds of sneaky marketing ploys, subscription traps, and discounted items that are hardly discounted at all. Redditors shared some of the top frugal sins in this thread, and now we’re on the lookout for more ways we’re making major mistakes with our money.

1. Renting a Storage Unit — Only To Forget About It

The costs associated with maintaining access to your own storage unit can sneak up on you in a terrible way. If you don’t keep a watchful eye over your unit’s monthly cost, you could find yourself in a situation where you’re paying upwards of three times what you used to. Even if the cost of your storage unit remains steady, a smarter move might be to donate or sell your extra stuff for more money back in your pocket.

2. Using any Delivery App

Sure, we all have our off days. Maybe you woke up with a terrible cold, and the only thing that sounds good is soup delivered by Uber Eats or Grubhub. Getting food delivered should be a rare exception, though: Food delivery apps can cause a major dent in your financial health. 

3. ‘Buy Now, Pay Later’ Online Purchases

There are plenty of stores that offer “buy now, pay later” plans, but that doesn’t mean you should use ’em. If you’re unable to pay the balance off by the end of the month, you are setting your future self up for stressful times. Interest rates can creep up and pounce on you, and before you know it, you’ve dug yourself a hole that you will have a very hard time finding a way out of.

4. Financing a New Car That’s Beyond Your Means

Just don’t do it. Yes, a shiny new car is one of the ultimate ways to treat yourself. Maybe the unprecedented quarterly bonus hit your bank account, and you’ve achieved new heights of financial success. Slow down, though. Instead, pivot into investing that money, or even just continue building up your emergency fund. The monthly payments on fancy new cars can blindside you and really aren’t worth it.

5. Booking Separate Flights With a Tight Connection

This rings especially true for any time you plan to travel internationally and have connecting flights. If one of your flights is delayed, you could run the risk of missing the other flight booked through another airline, and may not be entitled to any recourse. If you opted for the basic fare, you might not even be able to get a refund. Sometimes spending more on travel is a way to ensure your money is secure.

6. Scratch-Off Tickets

This one falls comfortably under the umbrella of “frugal common sense.” Scratch-off tickets can seem harmless enough; for a few bucks, you can try your chance at winning free money for life. But the odds of you actually winning are pretty much non-existent. If you need a reminder, look for the odds that are often printed on the tickets themselves for a glaring reality check.

7. Adjustable-Rate Mortgages

Around 15 or so years ago, adjustable-rate mortgages (ARMs) were the talk of the town when it came to an alternative way to purchase a home. With an ARM in action, you could secure yourself a lowered interest rate over a shorter duration of time. After that time had passed though, your rate could shoot up annually — and at the market rate. 

Those higher mortgage rates could end up being your worst nightmare. And if you need any more info on what that can look like, just remember the time that the housing market caved in on itself in 2008.

8. Not Adjusting the Thermostat When You’re Gone

I get it. Nobody likes to suffer through the harsh cold of a bone-chilling winter or the heat of the summer inside their home. However, utility bills can throw your financial health in harm’s way very quickly. Remember to adjust your thermostat when you’re not at home — you can even leave sticky note reminders until it becomes second nature.

Meet the Writer

Matt has spent the last 8 or so odd years as both a writer and editor in Seattle and Brooklyn, where he is now based. He loves escaping the tirelessly fast pace of the “Mad Apple” that is NYC by taking walks and runs through parks where he’s able to catch up on the latest tea about society from the city’s ever chatty, always hungry, occasionally rabid, pigeons. When he’s not taking his urban nature strolls, or dutifully combing the deepest rabbit holes of the internet to find the content that’s worth sinking your mind’s teeth into, he’s likely holed up at a dark-lit dive bar with a book and/or some friends, or just easily he could be on the hunt for the next addition to his steadily growing plant family.
