Best Costco Brand Products

One of the main reasons Costco members are willing to fork over $60 or more every year just to shop: the club's beloved private label, Kirkland Signature. Many Kirkland products have earned a cult following for their high quality and low prices. Judging by rave reviews from experts and buyers, many of them are just as good as — maybe better than — name brands. So good, in fact, that Kirkland accounted for a quarter of Costco's revenue in the latest fiscal year, according to CNN. Here are some of Costco members' all-time favorite Kirkland buys.

Kirkland Signature Balsamic Vinegar

Kirkland Signature Balsamic Vinegar

$37 for two 1-liter bottles

Balsamic vinegar works great as a salad dressing and is the perfect salty companion to all kinds of recipes. But it can be pretty pricey at most local grocers, and it doesn't even come in a very big bottle. Costco, of course, solves that problem with these two 1-liter bottles. More than that, reviewers say it tastes fantastic. "Really enjoy the flavor, haven't found anything that it doesn't improve — fresh fruit, aged cheese, bottled pasta sauce, vanilla ice cream, homemade salad dressing," one writes. "Possibly not chocolate pudding (but then, we haven't tried it yet)."

We'd be remiss if we didn't mention one of Costco's best-known — and arguably most loved — products. These 3-pound birds manage to taste pretty darn good without the addition of MSG or gluten, and they are the runaway winner for both tastiness and value when compared with rotisserie chickens from other major grocery chains, notes Mashed.

Talk about something that it makes sense to buy in bulk. New parents have long sung the praises of Costco's baby wipes, saying they're sturdy, gentle on sensitive skin, and most importantly, cheap.

You might not expect to find high-end sheets in the same store where you buy your toilet paper in bulk, but buyers say Costco's sheets are the real deal. Made from 100% pima cotton, they have more than a high thread count going for them, including wrinkle-resistant technology and specially fitted corners. "They are bright white and beautifully luxurious, but feel light as a feather on and sleep cool," one buyer says in a review.

Costco's bagels have earned a thumbs-up from Consumer Reports, which says they're just as good as what you pay more for at Dunkin'. They're fresh, which helps make them even tastier, but as Redditors note, that also means that they are quick to expire.

Repeat buyers say it's hard to beat the quality for the money. "Even though this shirt is so inexpensive, it is just as high quality as those I have paid $50-100 for," one reviewer says.

As Consumer Reports notes, there's no reason to overpay for the same active ingredient.

Shoppers feel so passionate about this seasoning that they led a revolt when it was removed from Costco shelves, eventually prevailing in getting it added to the website instead.

I use this seasoning on chicken thighs, shrimp, even ribs."
