Runner-Up: Kirkland Signature Sparkling Water Bottles

sparkling bottles

Price: $10.69

Who knew zero calories could taste so good? We’re impressed by the bold taste of this three-flavor pack. Get eight black raspberry, eight kiwi strawberry, and eight orange mango in each pack. The 17-ounce bottles are dupes for Ice’s brand-name buy. Compare $10.69 for 24 of the Kikrland generic to $11.39 for 12 of the real deal from Target.

Runner-Up: Kirkland Signature Cold Brew Coffee

cold brew coffee

Price: $18.99

Pass on pricey barista blends and try this bottled KS cold brew instead. This made our list for a few reasons — including taste, convenience, and cost. Snag 12 of the 11-ounce ready-to-drink cans for less than $19.

Target sells one 9.6-ounce Starbucks Nitro Cold Brew Coffee Drink for $3.99. You would need to pay over $47 for Costco’s quantity at that price.

Runner-Up: Kirkland Signature Organic Unsweetened Vanilla Almond Beverage

unsweetened vanilla almond beverage

Price: $9.99

No dairy? No problem. You won’t have to worry about lactose with this almond beverage. And that’s why it made our runner-up list. But we also picked this product for its price. The six-count of 32-ounce containers is less than $10, while Whole Foods Market sells 32 ounces of the 365 store-brand Organic Unsweetened Vanilla Almond Milk for $2.79.

Runner-Up: Kirkland Signature Sport Drink

sport drink

Price: $12.99

Replenish your electrolytes for less. This 24-count variety pack of Kirkland’s post-workout drink includes 20-ounce bottles of Fruit Punch, Blue Raspberry, and Orange flavors. Target sells a mixed assortment from Gatorade for $11.39. Even though this price is less, you’ll only get 18 of the brand-name’s 12-ounce bottles.

Runner-Up: Kirkland Signature Organic Lemonade

organic lemonade

Price: $7.49

A refreshing glass of lemonade beats almost every drink we spotted at Costco — landing this affordable organic near the top of our list. And shoppers agree. Customer Sue L. gave this budget-friendly beverage a five-star review, “The best bottled lemonade I have ever had…Great on its own or mixed for Arnold Palmers or drinks! I keep this as a staple in my house.”

Runner-Up: Kirkland Signature Ionized Alkaline Water

ionized alkaline water

Price: $9.99

Kirkland’s Alkaline Water isn’t the same plain bottled beverage you always buy. Reverse osmosis and an ionization process give this purified product a pH of 9.5. And bonus, the water has added electrolytes for taste. Compare $9.99 for 18 one-liter bottles of the generic to $17.98 for 15 of Glaceau’s SmartWater at Sam’s Club.

Runner-Up: Kirkland Signature Diet Green Tea

diet green tea

Price: $10.49

We aren’t just fans of Costco’s iced coffee — we also adore the store’s iced tea. More specifically, the zesty citrus green tea. The zero-calorie beverage is a steal for $10.49. You’ll get 35 of the 16.9-ounce bottles for one low price. Target sells a 12-pack from Lipton for $6.99. In a price-per-bottle comparison, Kirkland comes out ahead at $0.30 versus $0.58 for the brand name.

Runner-Up: Kirkland Signature Organic Coconut Water

Price: $11.99

Save money on this runner-up. Get six 14-ounce refrigerated bottles of no-sugar-added 100 percent juice for under $12. A single 16-ounce size of Harmless Harvest Organic Coconut Water costs $4.89 from Target.

Runner-Up: Kirkland Canned Signature Sparkling Water

canned sparkling water

Price: $11.49

Leave calories, sodium, and sweeteners behind. This La Croix dupe is a bargain for $11.49. The multi-pack includes 35 of the 12-ounce cans in lemon, lime, and grapefruit flavors. Target’s eight-pack of lime La Croix costs $4.19 — or over $18 for Costco’s bulk buy quantity.

Runner-Up: Kirkland Signature Organic Orange Juice

organic orange juice

Price: $14.99

Make mimosas without breaking the bank. Save money on the juice and splurge on the champagne with this organic OJ. This double-pack includes two 59-ounce bottles, making it the perfect brunch party beverage.

Runner-Up: Kirkland Signature Vita Rain Zero

vita rain zero

Price: $12.49

Vitamin-enhanced water is a popular product that can add up. Six 16.9-ounce bottles from the Vitamin Water brand sell for $6.89 at Target ($1.15 per bottle). Kirkland’s generic 24-count is only $0.52 per 20-ounce bottle.

Winner: Kirkland Signature Food Court Cold Brew Mocha Freeze

food court cold brew mocha freeze

Price: $2.99

And the winner is…Kirkland Food Court cold brew mocha freeze. The KS Columbian beans and premium chocolate make this barista-ish beverage our favorite. But that’s not the only reason it came in at the top of our list. This delicious chilled drink is also an affordable alternative to Starbucks’ Chocolate Cream Cold Brew ($5.45 for a grande).

If you’re not in the mood for a caffeinated kick during your next shopping trip, the Food Court’s fruit smoothie is another top option to explore.

Bottom line

When it comes down to it, brand-name beverages aren’t always worth the cost. Instead of paying extra for trendy packaging and cutesy names, save money on groceries and try our favorite Kirkland signature drinks.

From a bubbly La Croix copycat to Food Court finds, our runners-up (and, of course, the winner) include something for everyone. And you don’t have to stop at the bottled beverage aisle. We spotted can’t-miss Kirkland deals on everyday essentials, prepared food, and more.
