10 Costco Dupes That Taste Just Like the Original

While many people have their go-to products from Costco, newer shoppers may not realize that some items are excellent dupes for popular name brands. You may be asking, how close can a Costco dupe actually be? The truth is, it’s often hard to distinguish Costco’s Kirkland Signature products from well-known brands. This is because many of these products are produced by the same manufacturers that create popular brands, sometimes with nearly identical ingredients. The biggest draw for Costco dupes is the significant savings. Pantry staples like peanut butter, hazelnut spread, and nut bars at Costco cost much less than their brand-name counterparts like Justin’s, Nutella, and KIND bars. But it’s not just food – Costco’s wine, liquor selection, and household goods like garbage bags and paper towels are all top-notch. If you want to save money without compromising quality, here are 10 Costco items you should add to your next shopping cart.

Kirkland Signature French Vodka

You might have heard that Kirkland’s Signature French Vodka is made by the same producer as Grey Goose. While the truth behind this rumor is uncertain, it’s tough for consumers to notice any difference. This French vodka is distilled five times and costs only a fraction of the name-brand price, without compromising on quality.

Kirkland Signature Nut Bars

KIND Bars are popular for their sweet, salty flavor and satisfying crunch. But why spend a few dollars per bar when you can buy a 30-count box for under $18? Kirkland Signature Nut Bars are gluten-free, free from artificial flavors, and packed with fiber and protein.

Kirkland Signature House Blend Whole Bean Coffee

Making coffee at home is a smart choice for several reasons: it’s affordable, healthier, and saves time. But if you’re missing your Starbucks trips, try a bag of Kirkland Signature House Blend Whole Bean Coffee. It was once roasted exclusively by Starbucks, and while that’s no longer the case, it still offers a bright and balanced taste that customers love.

Kirkland Signature Chinet Plastic Cups

Whether you're hosting a barbecue, celebrating a birthday in the backyard, or just hanging out with friends, Kirkland Signature Chinet Plastic Cups are essential. They come in a pack of 240, so you don’t have to worry about running out, and each cup holds 18 ounces—perfect for any drink you serve.

Kirkland Signature Italian Sparkling Mineral Water

Imagine sipping on sparkling water that tastes like San Pellegrino but at the price of a basic seltzer. Kirkland Signature Italian Sparkling Mineral Water is crisp, refreshing, and hydrating—whether enjoyed on its own or added to a cocktail. Plus, the value is unbeatable—just $33 for 24 bottles.

Kirkland Signature Organic Peanut Butter

Have you ever noticed that many peanut butter brands add oils and sugar to make the spread extra smooth and sweet? Kirkland’s Signature Organic Peanut Butter is simply made with dry roasted peanuts and a pinch of salt—no additives. It’s not only cleaner than most other brands, but it’s also more affordable. You can get two 28-ounce jars for just $12.99, which is comparable to the price of one jar from brands like Justin’s or MaraNatha.

Kirkland Signature Grass-Fed Butter

Believe it or not, you can taste the difference between regular butter and grass-fed varieties. If you’re looking to avoid paying a premium for brands like Kerrygold Irish Butter, try Kirkland’s version. This grass-fed butter is imported from New Zealand, and it comes from farms that are audited annually to meet strict quality standards.

Kirkland Signature Organic Greek Yogurt

This creamy, tangy organic Greek yogurt tastes just like premium brands such as Fage and Stonyfield, but at a much more attractive price. Whether you're making a morning parfait or using Greek yogurt in your baking and cooking, Kirkland’s version is definitely worth a try.

Kirkland Signature Hazelnut Spread

The only difference between Nutella and Kirkland’s Signature Hazelnut Spread is the type of oil used. Kirkland’s version is creamy, indulgent, and the perfect spread for desserts, crepes, or simply on toast.

Kirkland Signature Extra Virgin Italian Olive Oil

High-quality olive oils are often pricey, but Kirkland’s Extra Virgin Olive Oil is a standout exception. You can enjoy a smooth, buttery olive oil without the steep price tag. It’s perfect for everything from salad dressings to marinades and any meal you’re preparing.
