15 Things You Should Buy at Costco

Costco’s warehouse model offers unbeatable bulk pricing on high-quality items, making it a go-to for savvy shoppers. This guide covers 15 essential purchases that consistently deliver superior value, quality, and convenience over traditional grocery stores. Whether you’re stocking your pantry, planning meals, or handling household needs, these picks help stretch your membership fee while reducing overall expenses.

From Kirkland Signature products to fresh produce and prepared foods, Costco excels in categories where bulk buying shines. Parents, entertainers, and everyday households report significant savings on these items, often citing better quality and lower per-unit costs. Always compare prices, but data shows these 15 outperform competitors in most cases.

1. Toilet Paper

Toilet paper tops the list for Costco shoppers due to its massive packs and Kirkland Signature brand quality. A single purchase often yields 30-40 rolls at a fraction of supermarket prices per sheet, ideal for large families or frequent use. Parents rave about never running out, especially with kids, saving trips and impulse buys elsewhere.

  • Kirkland Ultra Soft: Comparable to Charmin but cheaper long-term.
  • Per-sheet savings: Up to 50% less than big-box retailers.
  • Bonus: Eco-friendly options available seasonally.

Household forums confirm non-food essentials like TP offer the highest value, with quality exceeding expectations. Stock up annually for peace of mind.

2. Almonds

Kirkland Signature almonds provide premium nuts at bulk prices that crush grocery store rates. A 3-pound bag costs far less per ounce, perfect for snacking, baking, or salads. Their freshness and size make them a staple for health-conscious buyers.

Rich in healthy fats and protein, almonds from Costco maintain crunch without added oils. Community favorites include unsalted varieties for versatility.

3. Olive Oil

Costco’s extra virgin olive oil, often Kirkland or imported brands, delivers restaurant-grade quality in gallon jugs. Prices per ounce beat specialty stores by 40%, essential for cooking, dressings, and marinades.

Opt for cold-pressed varieties to preserve antioxidants. Shoppers note consistent availability and no rancidity issues common in smaller bottles. Pair with avocado oil for variety, as recommended for holiday cooking.

4. Soda (and Beer)

Bulk soda packs and beer cases at Costco offer party-ready quantities at low per-can prices. Kirkland sodas rival name brands in taste, while beer selections include crafts at wholesale rates.

  • Ideal for entertaining: 36-packs under $12.
  • Alcohol savings: Rotate selections for events.

Non-alcoholic options like sparkling water add value for families avoiding sugar.

5. Soy and Almond Milk

Plant-based milks in Costco’s large cartons provide extended shelf life and lower costs per serving. Almond milk packs yield smoothies, cereals, and coffee at half the price of single cartons.

Soy milk appeals to vegans, with organic options available. Freezing extras prevents waste in multi-person homes.
