5 Household Items You Shouldn't Buy Based on Price Alone: Experts Reveal the Truth—Saving Small Money Could Cost You More

5 Household Items You Shouldn't Buy Based on Price Alone: Experts Reveal the Truth—Saving Small Money Could Cost You More

### When Buying Household Goods, These 5 Items Shouldn’t Be Chosen Solely by Price

When purchasing household items, many people habitually compare prices, hoping to save money whenever possible on products with similar functions. However, some items are used frequently and may involve electricity, water leakage, or home safety. If you only choose the lowest-priced option while ignoring safety standards, core materials, and durability, you may end up incurring higher costs later for repairs, installations, or repurchasing.

Which household items shouldn’t be selected based solely on price? Drawing from testing data and expert insights from Taiwan’s Bureau of Standards, Metrology and Inspection (BSMI), the U.S. nonprofit consumer organization Consumer Reports, and the home repair media outlet This Old House, the following five household products have more important considerations than price when making a purchase.

### 1. Extension Cords

Extension cords may seem inexpensive, but they are one of the household items that remain connected to electricity for long periods and must not overlook safety specifications.

On July 17, 2024, the Bureau of Standards, Metrology and Inspection (BSMI) released test results for commercially available extension cords. In March of the same year, BSMI randomly purchased eight different brands and models of extension cords from large retailers and home appliance stores for testing. The results showed that one product failed the “quality item” test, two failed the “critical component comparison” test, and one failed the “label verification” test.

BSMI reminds consumers that extension cords are designated as mandatory inspection items. When purchasing, consumers should confirm that the product bears the “commodity inspection mark” and check the manufacturer information, voltage, current, and power specifications.

Users should also pay attention to the rated current and power limits to avoid overheating, short circuits, or even fires caused by overloading. BSMI explicitly warns against using extension cords with high-power appliances such as hair dryers, ovens, and electric heaters.

Therefore, when buying extension cords, what should take priority over price are the commodity inspection mark, rated current, power rating, and clarity of product origin. Saving a few dozen dollars isn’t worth it if it means compromising on unclear specifications or inadequate safety.

### 2. Faucets

Faucets may look similar on the outside, but the parts that truly affect long-term durability are often hidden inside.

The U.S. home repair media outlet This Old House updated its faucet buying guide on May 25, 2026. It states that common faucet body materials include solid brass and zinc alloy. Solid brass generally offers better corrosion resistance and durability, while zinc alloy, though typically more affordable, may not match brass in long-term corrosion resistance.

The article also cites the opinion of plumbing professional Kevin Bilo. Bilo points out that product weight can be one clue to judging faucet quality. Products with cast bronze or brass valve bodies are typically more durable and less prone to problems than those using lightweight components.

He also recommends paying attention to the internal valve cartridge. Products with ceramic-disc cartridges generally withstand wear better than older washerless valve cartridges when exposed to minerals in water pipes.

Therefore, when choosing a faucet, don’t just compare appearance and price. Also check the body material, type of valve cartridge, warranty terms, and whether replacement parts are available for future repairs.

After all, if a faucet starts leaking, the repair cost may extend beyond the faucet itself. Long-term seepage could also increase repair costs for surrounding cabinets and countertops.

### 3. Paint

Paint is one of the easiest household items where “cheaper per can” doesn’t necessarily mean “cheaper overall.”

The U.S. nonprofit consumer organization Consumer Reports updated its paint buying guide on July 31, 2025. In laboratory tests, they evaluate whether a single coat of paint can adequately cover a darker underlying color.

According to the test results, economy-grade interior paints generally perform poorly and may require 3–4 coats to cover dark walls. In contrast, higher-performing premium paints often achieve sufficient coverage with just one coat for most colors.

This is the hidden cost that focusing solely on “price per can” tends to overlook. If the paint is cheap but requires two or three additional coats, not only does paint consumption increase, but you also spend more time if doing it yourself. If hiring professionals, labor costs may also rise.

Therefore, when buying paint, a more practical approach than comparing only the price per can is to consider coverage, total area per can, scrub resistance, and the number of coats required.

### 4. Door Locks

Door locks shouldn’t be judged solely by whether they “can open and close,” because different products may have significant differences in resistance to forced entry.

Consumer Reports updated its door lock buying guide on January 21, 2025. They conduct laboratory tests on traditional deadbolts, electronic locks, and smart locks, including kicking doors, lock-picking, and drilling into the lock cylinder.

Test results show that, except for a few high-security locks, most tested locks can have their cylinders destroyed by a cordless drill in two minutes or less.

Consumer Reports also found that the lock itself isn’t the only critical factor. Many locks come with a strike plate—the metal plate installed on the door frame that receives the bolt—secured with short screws. Experiments found that replacing the original part with a sturdier box strike plate and securing it with 3-inch-long screws significantly improved most tested locks’ resistance to kicking.

Door lock test engineer David Trezza stated in the report that manufacturers should provide more robust hardware, and locks should be secure by design, without requiring consumers to upgrade them after purchase.

Additionally, some imported door locks are labeled with “Grade 1, Grade 2, Grade 3.” It’s important to note that this is a common performance classification under the U.S. ANSI/BHMA standard system and not adopted by all door locks in Taiwan.

Official data from the U.S. Builders Hardware Manufacturers Association (BHMA) shows that many ANSI/BHMA standards classify products into Grade 1, 2, and 3, with Grade 1 representing the highest performance level. Each grade must meet corresponding performance test requirements.

Test results also show that this industry classification generally aligns with their findings, with Grade 1 locks typically being the most difficult to break.

### 5. LED Light Bulbs

Although LED bulbs are low-cost individually, many people tend to compare prices directly when purchasing. However, for these products, inspection marks and specifications should be the top priorities.

According to BSMI’s test results for commercially available LED bulbs, published on October 27, 2025, BSMI randomly purchased 10 different brands and models of LED bulbs from electrical stores and large retailers in 2025 for testing.

The results showed that all 10 products met the requirements for “commodity inspection mark” and “Chinese labeling,” but one product failed the “quality item” test.

BSMI stated that LED bulbs are now included in the list of mandatory inspection items and must complete relevant inspection procedures before being sold on the market.

Officials also remind consumers to check for the “commodity inspection mark” when purchasing LED bulbs and to verify the manufacturer’s name, address, phone number, model number, voltage, power consumption, or current specifications.

Therefore, when buying LED bulbs, more important than simply finding the lowest-priced option are the product’s origin, inspection mark, specifications, and clarity of quality.

### Cheap Doesn’t Always Mean Bad—What Really Matters Is the “Total Cost”

“Don’t buy too cheap” doesn’t mean you should always pick the most expensive household items. It’s a reminder to consumers not to treat the lowest price as the sole criterion.

When purchasing such items, prioritize confirming these four things:

- Are the required safety inspections, labels, or certifications complete? - Are the core materials, components, and product specifications clearly stated? - Is durability, warranty, and future repair support guaranteed? - Are consumable, labor, repair, and replacement costs included in the total cost calculation?

The real way to save money isn’t necessarily buying the cheapest option right now, but finding, within your budget, a product with appropriate safety standards, clear quality, and long-term reliable performance.
