'Costco relaxes my soul': 6 die-hard Costco fanatics explain why they love the warehouse store so much

Most Costco fanatics agree that the in-house food court is one of the best features of the store.

"I used to go there when I worked and eat a salad for lunch at least once a week." said the Costco fanatic from Colorado, who praised the quality of the food as well as the low prices.

For young kids, the food court at Costco is especially exciting. "You can get pizza or a hotdog, or a soda and ice cream," said Matt, founder and editor of Costco Insider, a website that lets users know about upcoming deals and changes in Costco stores across the US. "And so there's a lot of food that parents are willing to buy because it's super cheap and it's convenient and kids love it."

Denise, a mother of four who started a Facebook group for Costco fanatics in California and Nevada, said the food court is one of her favorite features of Costco.

"[It's the] cheapest dinner, lunch I can get my kids," she said. "I can feed all of us for $12!"

Costco's in-house Kirkland Signature brand goes hand-in-hand with its low prices.

Ellinger refers to products from the brand as "the fruit of Costco."

The Kirkland brand appeals to people who want affordable products with a guarantee of quality. The brand includes food, shampoo, clothes, and more.

"I love the Kirkland brands!" Denise, who said she has purchased Kirkland diapers and underwear for her kids.

Denise, like other Costco-lovers, also appreciates the return policy associated with Kirkland and other Costco products, which guarantees satisfaction or your money back.

Dan, the Los Angeles Costco fan, also praised Kirkland Signature goods, though he mentioned he has a limit: "The only thing I can't bring myself to purchase are Kirkland Signature pants."

Costco's free samples in its food sections are a huge crowd-pleaser.

Matt from Costco Insider takes his one-and-a-half-year-old daughter to Costco regularly and finds the free samples to be extremely helpful. "It's great for me as a parent because I can have her try a bunch of different foods that she's never tried before and find out what she likes before I buy it."

Denise, also a parent, agreed that the samples are great and delicious.

Even for people without kids, members say the free samples are a nice in-store treat.

Shopping features aside, there is something more to Costco that cultivates such a loyal fan-base.

"Costco relaxes my soul," said John, the founder of the I love Costco blog. And he's not alone in his sentiment.

"I do love that everyone at Costco appears to be relaxed humans," said Ellinger. "I love overhearing a weird personal conversation between two employees unloading a box and knowing that Costco is a safe space for people to just be people."

With such a large selection, Costco has the ability to permeate every sector of life. Matt from Costco Insider proposed to his wife with an engagement ring from the warehouse store. Ellinger had a birthday party in the Costco food court and once took a date on a trip to the warehouse.

At its core, however, Costco is still just a store, selling everything one could need to survive in bulk.

And for many fanatics, that much is enough. As a Colorado fanatic put it: "Who wouldn't love that?"
