There are a staggering 71 million paid Costco members worldwide, and it's safe to assume that each has their own reason for paying for a membership. Some people drop by the warehouse store to pick up the same specific items each month. Others like the thrill of the hunt, strolling the store to learn what's new. No matter which camp you fall into, it's always nice to find a bargain. Here are seven amazing buys for June 2024.

1. Squishmallows 20" Hello Kitty Plush

Costco price: $19.97

Mercari price: $33.25

We'll start with the much-loved, sometimes-maligned Squishmallows. Kids love them, while the adults in their lives have been known to ask, "Where are we going to put this thing?" Squishmallows have been popular for a couple of years now, but it's not always easy to find a good price on one. Recommended for ages 3 and up, Costco's latest Squishmallows feature one dressed in (bright!) pink plaid and another wearing the same bright pink bow and holding a hamburger.

2. Honeydew Ladies' 2-piece Pajama Set

Costco price: $9.97

Amazon price: $54

If the pandemic taught us anything, it's that pajamas are not just for nighttime. During those months of pod living, we learned the joy of living in leisure clothes, eventually morphing into wearing our favorite pajamas all day long. We may not get the same opportunities to rock our best pjs now, but that doesn't make us love them any less. This set is both soft and functional, with side pockets to tuck away a phone. Designs include animal prints, camouflage, and polka dots. Available in sizes X-Small to 3X.

3. trunature Verisol Collagen Powder 2,500 mg.

Costco price: $14.99 through June 30, 2024

Walmart price: $25.91

Thanks to celebrities and influencers, collagen supplements have become all the rage. Collagen devotees say it may improve skin, hair, and nails. Collagen also gets props for helping improve joint function and making bones denser. To be clear, trunature does not make these claims. Still, if you've had a positive experience with a collagen supplement, you may want to take advantage of this low price. And if you have an eye on your personal finances but want to give collagen powder a try, this may be the opportunity you're looking for.

4. Quiksilver Men's Volley Swim Short

Costco price: $18.99

PacSun price: $33.75

These men's swim trunks have a couple of features one would expect in a swim trunk: 4-way stretch fabric for easy movement and a built-in liner. What's more surprising to anyone who's ever shopped for them is that they're actually quite attractive. With three eye-catching designs, they're available in sizes Medium to 3X.

5. ThermoFlask 24 oz. Stainless Steel Insulated Water Bottle (2-pack)

Costco price: $16.97

Walmart price: $25.99

If you're trying to help the environment by moving away from plastic bottles, it would be tough to find a better deal on 24-ounce insulated water bottles than this. They're made of double-walled vacuum-insulated stainless steel and come with a universal lid that fits all wide-mouth ThermoFlask bottles. In addition, they are BPA-free and dishwasher-safe.

6. Kirkland Signature Extra-Large Absorbent Pads (100-count)

Costco price: $19.99

Tractor Supply Co. price for a leak-free product of similar size: $32.99

Whether you have a puppy or an older dog, you know how invaluable absorbent potty pads are. At 30" by 23", they're large enough to use for potty training or bedding. And, at $19.99, you'll only spend $0.20 for each leak-free pad.

7. BIOHEAL BOH Vitamin Toning All Melting Cleansing Balm – 2-pack

Costco price: $18.99 through June 30, 2024

eBay price: $24.50

If you've never washed your face with a cleansing balm, you've been missing out. As it melts into your skin, you can practically feel it removing the impurities. BIOHEAL BOH is made with lipohydroxy acids (LHA) to gently exfoliate the skin and polyhydroxy acids (PHA) to clean while protecting the moisture barrier. The formula is hypoallergenic and suitable for all skin types.

The fun thing about Costco is the massive variety of products. There truly is something for everyone. If you're fortunate enough to find something you like that fits your budget , it's nothing short of a win-win.
