Costco has 817 warehouses and 111.6 million member cardholders worldwide, and those members likely will attest to the same thing: Costco has quality products at consumer-friendly prices. Households in the U.S. shell out $60 a year for a Gold Star membership to take advantage of the warehouse prices on everything from milk to mattresses and dog food to diamonds.

Nuts

Costco shoppers are nutty about the store's nuts. So are the team members who source and purchase the products for the shelves. To bring a 2-pound bag of Kirkland Signature Heart Healthy Mixed Nuts, the buyers worked with suppliers of almonds, pistachios and walnuts in the San Joaquin Valley of California, and then turned to hazelnut suppliers in Turkey to find the finest quality of that nut to add to the mix, according to the Costco Connection magazine.

And the nut prices are legendary. On the store's website, Kirkland Signature Unsalted Mixed Nuts are listed at $17.49 for 2 1/2 pounds. At Whole Foods, the 365 Everyday Value Roasted & Unsalted Deluxe Mixed Nuts cost $8.99 for 16 ounces. Buying them at Costco is like getting almost a half-pound for free.

Cake

The Costco brass learned in mid-2020, shortly after the start of the coronavirus pandemic, not to mess with success. Or cake. For years, the Costco half-sheet cake has been immensely popular, but when the pandemic hit and big gatherings ceased, Costco pulled the under $20 cake from its offerings. Who needed a cake to serve 48? Americans revolted, started a petition drive through Change.org and got their beloved treat back. Fun fact: A Costco half-sheet cake weighs more than 9 pounds.

Alcohol

In most states, you can buy alcohol at Costco even if you don't have a membership, and people flock to the warehouses to take advantage of a high-quality product at a low price. Speculation long has abounded as to who makes Costco's Kirkland house brand wines and liquors, but actual manufacturers remain a mystery. In a February 2021 article, Thrillist tried mightily to come up with the answers, and its expert couldn't precisely name the manufacturer but compared several Kirkland products favorably with the biggest names in liquor.
