13 Walmart Items Priced So Good We Had to Do a Double Take

While finding high-quality products at bargain prices may feel like looking for a needle in a haystack, you're usually in luck if you head to Walmart.

Known for everyday low prices, the retail giant still manages to surprise you with deals that may make you wonder if the price tag is missing a digit.

If you want to save money at Walmart, this one's for you. Here are 13 deals with prices so affordable, you'll find yourself double-checking to make sure they're real.

Editor's note: Prices and availability are subject to change and may vary by location.

Price: $394

The Sealy mattress has an unbeatable price for the comfort and support it provides with its specialty breathable foam and response-encased coils.

Once you try it, you'll find it hard to go back to paying $1,000 or more for brand-name hybrid mattresses like the Casper Sleep Nova. And why should you?

Price: $26.49 (on sale from $35.99)

Essential oil diffusers can improve your mood and make your home smell like a spa. This Daybetter product doubles as a humidifier for your home, which is a must-have during dry winters. It also has seven RGB night lights.

It's also a steal at its current sale price. A simple diffuser without extra functions sells for $40 at Target.

Price: $9.46

Paper towels have a tough job of taking care of spills, eliminating dirt, and keeping your kitchen in top shape. Then, they're unceremoniously thrown in the garbage, their job done.

Paying a premium for brand-name paper towels, like Bounty towels, which cost $7.32 for two triple rolls, is wasteful. At $9.46 for six double rolls, the Great Value offering can only be beaten by reusable cloth towels, but that's a different story.

Price: $1.06

Equate Hydrogen Peroxide has the same concentration of active ingredients, 3%, as all other similar products on the market.

At $1.06 per 32 fluid ounces, it's the perfect addition to your first aid cabinet without paying $8.99 for the Viva Doria brand at half the size.

Price: $49 (on sale from $99.99)

The Shark VACMOP offers you a combo of powerful vacuuming and spray mopping that makes cleaning a breeze, especially if you have many hard floors in your home.

Getting it for less than $50 is the way to go if you want to take advantage of this powerful cleaning tool. The same model costs $59.99 on sale on Amazon, so this is a no-brainer.

Price: $116 (on sale from $129.99)

With summer finally here, you may be looking for an extra freezer to store your ice cream, popsicles, and other frozen treats. This small Arctic King unit is perfect for the job.

A similar capacity Frigidaire upright freezer is available from Amazon for $186.75, but why pay more for the same features?

Price: $3.46

This pantry staple is kosher and comes in a four-pound easy-to-store bag. Like other Great Value products, it guarantees high quality at an affordable price.

Once you buy it, you'll realize that there's no point paying an extra dollar for four pounds of Domino granulated sugar or other premium brands.

Price: $14.97

The Mainstays six-piece towel set includes two bath towels, two hand towels, and two washcloths. It comes in five colors and is made of 100% cotton, with strong water absorbency.

Its price is a far cry from the $62.10 that the viscose cotton six-piece towel bundle by Blue Nile Mills commands at Target.

Price: $10.44

If you're planning to go camping this summer, this BPA-free, 22-ounce steel tumbler will keep your beverages as hot or cold as you want them.

It's easy to carry and fits in most car holders, doing everything that the Yeti Rambler does for $35, or more than three times the price.

Price: $6.88

Carbonara ramen is a bit of an acquired taste, but if you love this Samyang ramen flavor, you'll be happy that Walmart sells a five-pack for under $8.

Why should you stock up? The same amount costs $8.69 at Target and $12.99 at Amazon.

Price: $5.47

This 40-pack water package is a great addition to your camping supplies or snack box. The half-liter bottles are easy to carry, and water is vastly superior to soda during the summer heat.

Water is water, right? That's exactly why you should choose the Great Value pack over the Kirkland Signature Purified Water 40-pack, which sells for $19.75 on Amazon.

Price: $69 (on sale from $89)

Getting an air fryer is a safe way to eat healthier, and the Ninja brand is one of the most celebrated air fryer brands out there today.

You won't find the four-quart Ninja fryer for cheaper anywhere else. The same model sells for $103.48 on Amazon.

Price: $7.92

Upgrading your bedroom? Consider these two Mainstays standard (queen) pillows for only $7.92. With their hypoallergenic, antimicrobial fill and properties and soft microfiber cover, they're the recipe for peaceful sleep.

They can beat any high-end pillows, including the down pillow from Room & Board, which costs $129 for the standard size. Unlike down pillows, they're also machine-washable.

With these amazingly affordable Walmart items, it's easy to avoid wasting money on everyday essentials and even home and pantry staples.

Another way to save money at Walmart is to scan each barcode with the iOS or Android app on your phone. This way, you'll see the most recent, hidden clearance prices that haven't yet been updated on the shelf.
