Look, I love a dollar store. I’ve walked out of Dollar Tree with bags full of cleaning supplies, greeting cards, and party decorations feeling like I just pulled off some kind of heist. But after years of shopping there — and years of getting burned (sometimes literally) — I’ve learned that some aisles are best avoided entirely.
Not everything cheap is a deal. Some dollar store items cost you more in the long run because you’re replacing them constantly. Others are straight-up safety hazards. And a few might actually be more expensive per unit than what you’d pay at Walmart or your regular grocery store.
Here are the seven things I will no longer touch at the dollar store — and where to get them instead.
1. Batteries — They’re Old, They Leak, and They Die Fast
This is the one that gets everyone. You see a pack of AA batteries for $1.25 and think, why would I ever pay $12 for Duracells? Here’s why: those dollar store batteries are often carbon-zinc instead of alkaline, which means they hold less charge, die faster, and are more prone to leaking acid inside your stuff.
Even the packaging gives it away. Look at those packs of “heavy duty” batteries at Dollar Tree — the e-Circuit and Panasonic ones often say right on the label that they’re only intended for low-drain devices like remotes and clock radios. That’s a polite way of saying they can’t handle much.
There’s also a shelf-life problem. Dollar stores often get their batteries as overstock from other retailers. So that pack may have already been sitting at a Target for three years before it landed on the dollar store shelf. Batteries lose charge even when they’re unused.
Your best bet: Buy alkaline batteries in bulk at Costco (the Kirkland brand is solid) or grab Energizer or Amazon Basics packs during sales. The per-battery cost ends up being about the same, and they’ll actually work when you need them.
2. Extension Cords and Phone Chargers — A Genuine Fire Risk
This isn’t me being dramatic. Over 1 million Crafter’s Square hot glue guns sold at Dollar Tree were recalled because they could malfunction and catch fire. Dollar stores have also recalled extension cords and decorative lights for the same reason, according to the Consumer Product Safety Commission.
The problem is thin, cheap wiring. Dollar store extension cords, power strips, and phone chargers use thinner gauge wires that can’t handle normal power loads. One loose connection is all it takes. A shopping expert interviewed by AARP put it plainly: they may work in a pinch, but they aren’t going to last long — and the risk isn’t worth the $1.25 you saved.
When the Ecology Center in Ann Arbor tested dollar store electronic accessories, many tested high in chlorine — a toxic chemical concern and a sign the items are made from vinyl. For anything that plugs into your wall, spend the extra $8-$15 at Home Depot or Target and get something from a brand with actual safety certifications (look for the UL listing).
3. Plastic Food Containers — Cheap Plastic, Real Chemicals
Here’s the thing about plastic food containers: not all plastic is the same. The cheap stuff at dollar stores is more likely to contain phthalates and bisphenol-S (BPS), which can leach into your food — especially when you heat them up in the microwave. And let’s be honest, that’s exactly what most of us do with leftover containers.
Flip the container over. If you see a number 7 on the bottom, it likely contains BPA. You’re not going to find BPA-free or food-grade certified containers at the dollar store. They just don’t exist in that price range.
If you want to use dollar store containers for storing craft supplies, screws, or random junk drawer items? Go for it. That’s actually a great use for them. But for anything that touches your food — especially hot food — grab a set of glass containers from Walmart or a Pyrex set from Target. A 10-piece set runs about $20 and will last you years.
4. Tools — A Dollar Hammer Gives You Dollar Results
I once bought a screwdriver set from Dollar Tree to fix a loose cabinet hinge. The Phillips head stripped on the second screw. Not the screw — the actual screwdriver tip rounded off. That was the last time I bought tools there.
Dollar store tools — screwdrivers, tape measures, wrenches, hammers, paint brushes — are made from the cheapest possible materials. They bend, break, and frustrate. A tape measure that won’t retract. A wrench that slips. A paint brush that sheds bristles into your wet paint. They are cheap, but so is the quality, and they will do nothing but frustrate you over time.
Quality tools come with warranties. A basic screwdriver set from Craftsman at Lowe’s runs about $15 and has a lifetime guarantee. Even Harbor Freight’s budget tools are significantly better than what you’ll find at the dollar store. When something breaks mid-project and you have to stop everything to go buy a replacement, you didn’t save anything.
5. Oven Mitts — Thin Material, Real Burns
An oven mitt has one job: keep your hands from getting burned. Dollar store oven mitts are often so thin you can practically feel the heat radiating through them before you even pick up the baking sheet. In 2021, Health Canada actually recalled oven mitts sold at a discount chain because they were melting and catching fire.
A proper oven mitt should protect your hands from 400-degree temperatures for at least 10 seconds. The ones at dollar stores don’t even come close. You’ll grab a casserole dish, feel the heat immediately, flinch, and that’s how dishes get dropped.
If you spot cute seasonal oven mitts at the dollar store, use them as decoration — hang them on a hook in the kitchen. But for actual cooking, spend $10-$15 on a real pair. Silicone oven mitts are heat-resistant, waterproof, and won’t melt on you. They’re one of those things where the price difference between useless and reliable is small enough that there’s no excuse to cheap out.
6. Skin Care, Makeup, and Hair Color — Not Where You Want to Cut Corners
A year-long study from the Campaign for Healthier Solutions tested nearly 220 products purchased at dollar stores across the country and found 46 items containing harmful chemicals, including formaldehyde-releasers in baby lotion and lead traces in various products.
Dollar store makeup is almost always an unfamiliar off-brand, and the cheaper ingredients are more likely to cause allergic reactions, rashes, or breakouts. One shopping expert explained that the materials in these products are processed on a low budget and aren’t refined well for skin contact. Hair color is even riskier — an unknown $1 box of dye could leave you with damaged, fried hair and a trip to the salon that costs 50 times what you saved.
Then there’s the expiration issue. Dollar stores frequently sell factory closeouts, which means that bottle of lotion or tube of foundation might be well past its prime. If you don’t see an expiration date, walk away. Walmart’s beauty aisle and drugstore sales with coupons will save you money without the risk. And if you really want to check what’s in a product, download the Clearya app — it lets you scan barcodes and see what chemicals are lurking inside.
7. Paper Towels and Toilet Paper — The Math Doesn’t Add Up
This one surprises people because paper products seem like a perfect dollar store buy. They’re not. Here’s what happens: either you’re getting an off-brand product with fewer sheets, thinner plies, and weaker fibers — so you use three times as much — or you’re getting a brand-name product in a smaller package size that actually costs more per sheet than what you’d pay at the grocery store.
I did the math once on Dollar Tree paper towels versus a Costco pack of Bounty. The dollar store roll had about 40 sheets. The Costco pack came out to around $1.15 per roll — with over 80 sheets per roll of much thicker, more absorbent paper. You end up using one Bounty sheet where you’d need three or four of the dollar store brand. Same story with toilet paper. The cheap 1-ply stuff means you’re just folding and layering more, so you burn through rolls twice as fast.
Wait for sales at your grocery store or buy in bulk at Sam’s Club or Costco. Toilet paper and paper towels almost always go on sale around holidays. Stock up then and you’ll spend less per year than buying piecemeal at the dollar store.
What IS Worth Buying at the Dollar Store
I don’t want to leave you thinking dollar stores are all bad. They’re not. Some things are genuinely worth the trip. Greeting cards for $0.50 instead of $6 at Hallmark? All day long. Cleaning supplies like dish soap, sponges, and spray bottles are fine. Ziplock-style bags, tape, and hair ties are solid buys. Seasonal decorations and party supplies are where dollar stores really shine. And name-brand items like Colgate toothpaste or Dawn dish soap? If they have it, grab it.
The rule of thumb is simple: if it goes on your body, in your body, or plugs into your wall, skip it. If it’s disposable, decorative, or something you’d be annoyed to overpay for, the dollar store is your friend. Know the difference, and you’ll actually save money instead of just feeling like you did.
