When the sun’s out and the kids are home from school, the last thing you want to spend money on is household essentials. But stocking up now is the key to keeping your home running smoothly all summer long — and the smartest move is to buy in bulk.
Spoiler alert: The secret to saving on the “boring stuff” is simple. Just beeline for Kirkland Signature. Popular for good reason, this Costco-exclusive brand delivers quality products that rival name brands at a fraction of the price. Here are five of the best Kirkland Signature household items to add to your cart in May.
Kirkland Signature Ultra Clean Free & Clear Laundry Detergent
- Price: $19.99
Between soccer practice, camping trips and summer camps, things are bound to get messy over the summer. That’s where Costco comes in. The Kirkland Signature laundry detergent is gentle and effective for getting out tough stains — and strong odors — irritation-free.
With over 1,600 five-star reviews, this detergent is a favorite among families with sensitive skin and mess-prone kids. Hypoallergenic and free from dyes and perfumes, it’s $20 for 146 loads. That breaks down to just about $0.14 per load.
Kirkland Signature Paper Towels
- Price: $23.99
From sticky lemonade stands to colorful tie-dye DIY projects, summer spills don’t stand a chance against Kirkland Signature’s premium paper towels.
These sturdy and absorbent two-ply rolls are a Costco bestseller for a reason. With over 34,000 reviews and nearly five stars, they make cleanup a breeze. A surprising reason so many shoppers love them? Each roll includes smaller, half-sized sheets, so you can easily grab just what you need.
At $23.99 for 12 individually wrapped rolls, it’s a great value for serious cleanups.
Kirkland Signature 13-Gallon Kitchen Trash Bag
- Price: $19.99
Never double-bag your trash can again thanks to Kirkland Signature’s 13-gallon kitchen trash bags.
These bags have some nifty engineering that makes them surprisingly smart. Made of flex-tech plastic, they can stretch around the items inside, making them far more resistant to sharp objects or leftovers gone rogue. No tearing. No leaking.
Each box of 200 costs about $20. That’s a wallet-friendly price of $0.10 per bag to keep messes (and smells) contained.
Kirkland Signature Cutlery
- Price: $18.99
Prep your pantry for the next backyard barbecue or birthday party with Kirkland Signature clear cutlery.
Summer pool parties are not the time to bring out the fine china. These plastic utensils are sturdy, disposable and perfect for large gatherings. Even better? They won’t snap when slicing into a piece of steak, either. At about $19 for a 360-count of utensils, that’s enough to last you through the season — and then some.
They’re a bargain buy that’ll help keep summer events stress-free.
Kirkland Signature UltraShine Dishwasher Detergent Pacs
- Price: $13.99
If you’ve been splurging on name-brand dishwasher pods, it’s time to make the switch. Kirkland Signature UltraShine dishwasher detergent pacs cost just $0.12 per pod — and clean like a dream.
No more scrubbing dishes before loading or pulling out half-cleaned cups the next morning. With no prewash needed, these pods can handle food residue like a champ — even clean food that’s been stuck for up to 48 hours. Now that’s some serious cleaning power.
For $14, you get 115 pods, making it both time- and wallet-friendly.
