If you’ve ever hesitated to get a Costco membership because “it’s just me,” you’re not alone. Bulk shopping seems impractical for solo living—until you know which items are worth it. Some deals stretch further and actually simplify your week. Curious which ones make the cut? You’ll want this list before your next trip.
Kirkland Rotisserie Chicken

At just $4.99, Costco’s famous rotisserie chicken is a genius marketing move. It’s what insiders call a “loss leader,” meaning Costco makes little profit on it but wins your loyalty through unbeatable value. The real trick? Stretching one chicken into multiple meals and even using the bones for homemade stock.
Individually Wrapped Frozen Fish Fillets

Costco provides frozen fish fillets individually wrapped to maintain optimal freshness. Each portion can be thawed and cooked separately, reducing waste. This approach ensures flavorful, restaurant-quality meals whenever you want, whether cooking for one or preparing several servings for the week ahead
Single-Serve Coffee Pods Or Ground Coffee

Their single-serve pods are perfect for rushed weekdays, while the big bags of Kirkland Signature or national brand coffee are ideal for relaxed weekends. Either way, you’re getting top-quality coffee at a fraction of grocery store prices, which makes it a must-buy.
Bulk Nuts In Resealable Bags

Here’s a fun fact: nuts can stay fresh for six months if you store them right. Costco takes that knowledge seriously with its resealable bags of Kirkland nuts. Their premium nuts are also available both shelled and unshelled. These nuts stay crunchy and delicious, thanks to smart packaging that keeps air and moisture out.
Multi-Pack Protein Bars

If you love protein bars but hate overpaying for single ones, Costco’s multi-packs are a total game-changer.

Frozen Vegetables In Medium Bags

The medium-sized frozen vegetable bags are the perfect middle ground. They’re easy to portion and fit neatly in smaller freezers. Unlike the popular belief about frozen veggies, they are packed with nutrients as well. The technique used is just that you can stir-fry or grill them, and the meal will be ready in minutes.
Large Tub Yogurt With Portioning Containers

Each container offers up to a year’s supply at 20–30% less than pharmacy prices. From daily multivitamins to omega-3s and probiotics, it’s long-term health made budget-friendly.
Individually Wrapped Cheese Portions

Ever open a big cheese block only to realize half of it has gone bad? Costco’s individually wrapped Babybel and string cheese solves that problem. Each portion stays fresh until you’re ready to eat. These even slip easily into lunchboxes or backpacks and make snacking stress-free.
