So, we’re here to uncover the 12 hidden gems at Costco that shoppers swear by. These insider secrets will help you shop smarter, save money, and discover new products that’ll become your favorites.
1. Kirkland Signature Organic Extra Virgin Olive Oil
Kirkland, Costco’s private label, is known for delivering great quality at even better prices. One of their standout products is the Organic Extra Virgin Olive Oil. Professional taste testers have even compared it to high-end brands costing three times as much.
Not only is it a great value, but its quality is certified by the COOC (California Olive Oil Council). So, you’ll be getting a pure, unadulterated product. Whether you’re making a salad dressing or sautéing veggies, this olive oil is a pantry must-have.
2. Rotisserie Chicken
Costco’s Rotisserie Chicken is a busy weeknight dinner savior. Priced at just $4.99, it’s not only cheaper than most supermarket competitors, but it weighs more too.
While most rotisserie chickens weigh about 2-3 pounds, Costco’s bird weighs in at a whopping 3-4 pounds. That’s a lot of delicious, ready-to-eat chicken for an unbeatable price. Plus, it’s cooked in-house every day, so you’re guaranteed freshness.
