I've worked at Costco for 18 years. Here are 10 of the best things I'm seeing on the shelves this month.

• As someone who's worked at Costco for 18 years , I know which items are worth buying.
• The bakery's s'mores cookies are a tasty summertime treat inspired by the campfire classic.
• I recommend adding home items like the iDesign three-piece cosmetic organizer set to your space.

Like many fans of Costco, the leading retailer in customer satisfaction , I love browsing the shelves to see which items are worth taking home. The store has a great rotating inventory and competitive pricing, so it's no wonder why so many shoppers love the retailer.

I've worked at Costco for over 18 years, so I'm always searching for the best-value items at the warehouse. Here are 10 things I recommend checking out at Costco in June.

Prices may vary by location.

Make an easy meal with the Meat District chuck-and-brisket beef patties.

The Meat District chuck-and-brisket patties are perfect for easy grilling because they allow you to make burgers with less prep time and no mess. According to their packaging, the patties are made from premium steak cuts and seasoned with a garlic-peppercorn rub.

Each package, which contains eight burger patties, can be found in the cooler boxes at Costco's deli. At my Costco, a package costs $17.

The Titan 26-can backpack cooler is perfect for summer activities.

As summer approaches, these Titan 26-can backpack coolers with ice-wall pockets have been selling quickly at my location. The backpack features leak-proof lining and adjustable, padded straps.

They also come with two ice packs ready to be frozen, making them a great bag for outdoor use or even lunch storage. Each backpack is $45 at my location.

The Zuru Bunch O Balloons tropical party packs are an easy way to have fun with the whole family.

If you're looking for summer fun, check out the Zuru Bunch O Balloons tropical party pack, which features 490 self-tying balloons.

The stems on these balloons make filling them super simple — just attach a stem to a hose, fill it with water, and shake to make as many as 100 balloons in less than a minute.

My Costco sells packages of the Zuru Bunch O Balloons, which are seasonal, for $25.

I recommend grabbing the Kirkland Signature beef-and-pork meatballs with pasta and sauce from the deli.

The Kirkland Signature beef-and-pork meatballs with pasta and sauce is the newest premade item in Costco's deli, and it's delicious. Each container comes with rigatoni pasta, marinara sauce , and six giant meatballs, all topped with Parmesan cheese.

This meal is so easy to prepare. Everything is measured out, so all you have to do is set the oven to 400 degrees Fahrenheit, cover the tray with foil, place it on a cookie sheet, and bake it for 50 minutes.

The tray can feed about four people and costs $4.50 per pound, which comes out to about $20 per container.

Take care of fabric with the CHI electronic clothing iron with a retractable cord.

CHI is most popular for its hair products, but the brand also carries an electronic iron with a retractable cord. The iron features 400 steam holes and electronic temperature control.

The CHI iron costs $70 at my Costco.

Satisfy your sweet tooth with Kirkland Signature s'mores cookies.

Costco's bakery has been producing delicious seasonal items, including the Kirkland Signature s'mores cookies. The cookies are made with semisweet chocolate, graham flour, and marshmallows for a gooey first bite.

I find the best way to eat them is to microwave them for 10 seconds before taking a bite. Each package contains 24 cookies and costs $10.

Stand out among the sand with the licensed beach towels.

Costco is now carrying character-embroidered beach towels for the family. The towels come with four character designs: Hello Kitty, Stitch, Bluey, and Spider-Man.

These beach towels are 63-by-34 inches and machine washable. The sheared-velour towels are $18 at my store.

Add the iDesign three-piece cosmetic organizer set to your bedroom, bathroom, or closet space.

If you want to tidy up a space, the iDesign cosmetic organizer three-piece set could come in handy. The organizer is great to keep in a bedroom or even the bathroom.

The set contains two three-drawer organizers and a carousel organizer with a removable tray.

These organizers aren't dishwasher safe, but cleaning is as easy as getting a damp cloth and wiping them down. The iDesign cosmetic organizers are $39 at my store.

The SkinnyDipped dark-chocolate peanut-butter cups are a tasty treat.

The SkinnyDipped dark-chocolate peanut-butter cups are a tasty sweet treat. Each confection is coated with dark chocolate and loaded with peanut butter.

I like that this sweet treat has only 2 grams of sugar and less than 100 calories per serving. My Costco sells a 30-count bag for $14.60.

The Seville Classics bamboo two-tier sliding-drawer organizers can add elegance to a kitchen or bathroom space.

The Seville Classics two-tier drawer sets are perfect for under-the-sink, bathroom, and cabinet storage and allow easy access to your items.

The drawer set also features nonslip feet and a metal frame. These drawers are $34 at my Costco.
