I've worked at Costco for 19 years. Here are the 10 best things I bought there this year.

As someone with a small family who cooks almost daily, these Snapware Pyrex 18-piece glass food-storage sets came in handy all year.

Each set comes with nine airtight containers in various sizes that are leak-proof and microwave-safe.

The Shark Detect cordless stick vacuum is one of the best cleaning devices I've ever owned. At just over 6 pounds, it feels lightweight and is easy to haul up and down the stairs.

The Shark vacuum has four deep-cleaning modes and runs for up to 60 minutes, giving me plenty of time to tidy up. Each set also comes with a crevice tool and a multi-surface brush roll.

Even better, the device converts to a hand vacuum, making it easier to clean small, hard-to-reach places, car interiors, and staircases.

The Yummy Dino Buddies chicken nuggets are a great way for my kids to get their protein in. The chicken is juicy, and the nuggets get a slight crunch when air-fried.

To prepare them, I simply place some nuggets in the air fryer at 400 degrees Fahrenheit or microwave them for about a minute and a half.

If you shop at Costco, you may have seen kiosks from different cell-service providers when entering the warehouse. These kiosks usually offer deals on new cell-service plans and upgrades from carriers like T-Mobile, Verizon, and AT&T.

Depending on the carrier and warehouse, Costco customers who stop at the cell-service kiosks may also be eligible for members-only perks. For example, I got a $200 Costco shop card when I added a new phone line to my plan.

The Kirkland Signature rotisserie chicken has made making quick lunches and dinners easy.

Costco team members cook the rotisserie chicken fresh at the warehouse every day. I like to serve it with a side or shred the whole thing to use in meals like enchiladas or chicken salad.

At just $5 for a 3-pound chicken, it's one of the best deals out there.

The Arlo Essential XL wireless-camera bundle has been a good investment when it comes to feeling safe and at ease in our home.

This system is easy to install and has live HD video and color night vision. I also like that I can access the camera from my smartphone.

Each bundle comes with three cameras and a four-month Arlo secure subscription.

As a coffee fanatic, I know buying Keurig coffee pods can get pretty pricey. However, I feel I get a pretty good bang for my buck when I buy 120-count boxes of the Kirkland Signature K-cups.

The store carries flavors like breakfast blend and summit roast, but my family's staple is the Kirkland Signature organic Pacific Bold pods.

Getting new tires is a big purchase, but buying them from the Costco tire center was one of the best decisions I made this past year. The center offers various sizes from a few top-name brands, like Michelin and Firestone.

Not only do customers get wholesale prices, but the tire center also offers installation and inflation pressure checks.

Costco is the only place I buy my produce. Whether I'm getting berries, oranges, bananas, or even mangoes, the produce always seems to be high-quality and is sold at wholesale prices.

If you have a big family or know you'll be able to consume large amounts of fruit or vegetables before they go bad, I think it's worth buying produce in bulk.

Each year, I get an eye exam and purchase prescription glasses at Costco's optical center.

Customers can contact their insurance provider to check if the optical center's services are covered. However, you can still get an exam and purchase glasses if you're not covered by insurance — at my warehouse, out-of-pocket eye exams start at about $70.

Patients don't have to be cardholders to get an exam, but only members can purchase glasses or contacts.
