Scoring a great deal at a yard sale or thrift store can be satisfying—but not everything is a smart secondhand purchase. Whether it’s due to hygiene concerns, safety risks, or hidden damage, there are items you should never buy used, no matter how tempting the price. These products often wear out faster, carry unseen hazards, or simply lose effectiveness over time. While buying used can save you money, it’s important to know where to draw the line. Before you grab that “gently used” item, make sure it’s not on this list.
1. Cribs and Car Seats
Cribs and car seats top the list of secondhand no-gos for a reason: safety standards change constantly. Older models may not meet current regulations or could be missing key parts. Car seats, in particular, have expiration dates and may have been in an accident without visible damage. With children’s safety on the line, cutting corners isn’t worth the risk. For baby gear, always buy new to ensure full protection and up-to-date safety features.
2. Mattresses and Box Springs
No matter how clean a used mattress looks, you never really know where it’s been. Mattresses are notorious for harboring bed bugs, dust mites, mold, and bodily fluids. These pests and allergens can remain hidden deep inside the fabric and seams—even after cleaning. Once brought into your home, they can be nearly impossible to eliminate. When it comes to sleep and health, new is always better for your peace of mind.
3. Bike Helmets and Protective Gear
Bike helmets are designed to absorb a single impact—and then they’re done. If you buy one secondhand, there’s no way to tell if it’s already been compromised. Even minor drops can weaken the protective foam inside, reducing its effectiveness in a real crash. Similarly, knee pads, elbow guards, and similar gear lose their support and structural integrity over time. For something meant to protect your body, secondhand simply isn’t safe.
4. Non-Stick Cookware
Used non-stick pots and pans might look like a good deal, but they often come with hidden risks. Once the non-stick coating starts chipping or scratching, it can flake into your food. Older pans may also contain PFOA—a chemical once commonly used in non-stick coatings that has since been linked to health risks. It’s nearly impossible to know how a used pan was cared for. Investing in new cookware is a smart way to protect your health in the kitchen.
5. Makeup and Skincare Products
It might be tempting to grab discounted or barely used beauty products online or at a yard sale, but it’s a big no. Opened products—especially creams, mascaras, and lipsticks—can harbor bacteria, mold, and other contaminants. Sharing or reusing these can lead to skin infections, pink eye, or worse. Even if the product looks untouched, there’s no guarantee it’s been stored properly. When it comes to your skin and eyes, new is the only way to go.
6. Vacuum Cleaners and Small Appliances
Secondhand vacuums and small appliances often come with hidden wear and tear that affects performance. Internal parts like motors, belts, and filters may be on the brink of failure. Plus, you rarely get a warranty or guarantee when buying used. These items you should never buy used might cost less upfront, but end up needing costly repairs or early replacement. Spending a little more on new often means better efficiency and reliability in the long run.
7. Upholstered Furniture
Used sofas and chairs may seem like a steal, but they can carry more than just wear and tear. Like mattresses, they can hide bed bugs, fleas, allergens, and bacteria deep inside the cushions. Odors, stains, and smoke damage can also be impossible to remove completely. Even if it looks clean, it may have a long history you don’t want in your home. For anything with fabric, new is the safest bet.
8. Shoes and Footwear
Used shoes may look lightly worn, but every foot wears them down differently. Over time, the insoles and arches mold to the original owner’s feet, making them a poor fit for someone else. This can lead to blisters, foot pain, or posture issues. Plus, used shoes may carry bacteria or fungus that could cause infections. When it comes to footwear, buying new ensures proper support and hygiene.
Be Smart About Secondhand Shopping
While secondhand stores can be treasure troves for books, tools, and home décor, not everything should come home with you. Understanding which items you should never buy used can protect your health, safety, and wallet in the long run. New doesn’t always mean expensive—but when it comes to safety gear, bedding, or anything that touches your skin, it’s worth the extra cost. Smart shoppers know that saving money shouldn’t come at the cost of comfort or cleanliness. When in doubt, skip the deal and choose peace of mind.
