Costco’s bulk pricing can look tempting, but bigger packages do not always mean better value.
From fast-spoiling groceries to oversized household essentials, these purchases may cost more once waste, quality, and actual usage are considered.
Fresh Strawberries (and delicate berries) — Typically $4.99–$7.99+ for large packs
- Description: Large volumes often mold within days. Quality and flavor are inconsistent, and the “bulk deal” frequently leads to waste before the package is finished.
- Alternative: Buy smaller containers or loose berries at Aldi, Walmart, or your local grocery store—often fresher, cheaper per pound on sale, and easier to finish.
Bananas (bulk bunches) — Typically $1.99–$3.49 for large bunches
- Description: They ripen and spoil extremely fast in big quantities. Many households throw away a significant portion.
- Alternative: Purchase only what you’ll eat in a few days at a regular supermarket or Aldi. Freeze overripe bananas for smoothies or baking.
Avocados (bags or bulk) — Typically $0.99–$1.99 each or multi-packs
- Description: Hit-or-miss ripeness and quality. Bulk bags lead to bruising and waste; not significantly cheaper than other stores when you factor in spoilage.
- Alternative: Select individual avocados at your local grocery store so you can control ripeness and quantity.
Bagged or Bulk Organic Produce (e.g., organic apples, English cucumbers) — Often premium pricing
- Description: Frequently costs as much or more per unit than non-organic options elsewhere. Bags cause more damage, and you can’t inspect each item.
- Alternative: Shop regular or organic produce at Aldi, Trader Joe’s, or local stores where you can pick individually and often pay less.
Kirkland Signature Batteries (AA/AAA) — Typically $15.99–$18.99 for 48-pack
- Description: Widespread complaints about leaking (even unused or before expiration), shorter lifespan, and ruined devices. Recent batches have drawn consistent criticism.
- Alternative: Compare unit price on Duracell at Costco or buy trusted brands like Energizer in the quantities you actually need.
Bulk Spices and Seasonings (large containers) — Typically $5–$15+ for big jars
- Description: Lose flavor and potency long before most households finish them. They end up tasting bland or like “sawdust.”
- Alternative: Buy smaller jars from your grocery store or online specialists like Penzey’s for fresher spices in usable amounts.
Large-Format Condiments (e.g., 64 oz soy sauce, gallon mayo, big ketchup) — Often $8–$15+
- Description: Once opened, many spoil or degrade in quality before a typical household uses them up. Recipes call for small amounts.
- Alternative: Stick to standard grocery-store sizes, especially when they’re on sale or with coupons.
Kirkland Signature Bakery Bagels (dozen packs) — Typically $4.99–$6.99 for a dozen
- Description: Mold quickly for smaller households. Freezing changes the texture, and the bulk size often leads to waste.
- Alternative: Local bakery for fresher, right-sized quantities or smaller packs from regular grocery stores.
Pre-Cut Fruit or Vegetable Trays — Premium pricing, often $8–$15+
- Description: High markup for convenience. Shoppers report faster spoilage, sogginess, and occasional food-safety concerns.
- Alternative: Buy whole fruit and vegetables and cut your own—it’s cheaper and usually fresher.
Prepared Deli Items (e.g., pinwheel sandwiches, party platters) — Often $7–$12+/lb
- Description: Common complaints include bland flavor, soggy texture, and high cost per serving. The convenience premium rarely pays off.
- Alternative: Make simple versions at home or buy smaller portions from a grocery deli counter.
Raw Boneless Skinless Chicken Breasts (Kirkland) — Typically ~$2.99/lb or $19.99–$20+ for large packs
- Description: Frequent quality complaints (woody or funky texture). Some shoppers find better value and quality at other stores; rotisserie chicken gets far more praise.
- Alternative: Other grocery stores for better selection and pricing, or opt for chicken thighs or the popular Costco rotisserie chicken.
Kirkland Signature Diapers (large packs) — Typically $30–$40+ for 100–200+ count
- Description: Babies often outgrow the size before the pack is finished. Unit price isn’t always the best deal compared to other retailers.
- Alternative: Amazon Subscribe & Save (with discounts), Target or Walmart store brands on sale, or compare current unit pricing.
Laundry Detergent Pods — Higher cost per load
- Description: Significantly more expensive per wash than liquid or powder options. Bulk doesn’t always equal better value here.
- Alternative: Kirkland Signature liquid or powder detergent, or watch for sales on name brands at grocery stores.
Snack Variety Packs or Bulk Chips/Candy — Often $10–$20+ for mixed boxes
- Description: Small portions, unwanted flavors, and higher per-ounce cost than full-size bags. They often go stale before you finish the variety you don’t like.
- Alternative: Full-size bags of your favorites (portion them at home) or make your own snack mixes.
Large Bags of Flour or Baking Staples (e.g., 25 lb flour) — Varies, often cheaper per pound but risky
- Description: Goes bad (especially whole wheat), attracts pests, or sits unused if you’re not a heavy baker. Leaveners lose effectiveness over time.
- Alternative: Smaller bags at Aldi or grocery stores. Only buy large quantities if you bake frequently and store them properly.
Bulk Soft Drinks and Soda Packs — Often not the best value
- Description: Grocery store weekly sales and promotions frequently beat Costco’s everyday pricing for moderate use.
- Alternative: Shop sales at supermarkets or use the food court fountain drinks when convenient.
Oversized Pain Reliever Bottles (500–1,000 count) — Big bottles at lower per-pill price
- Description: Most households don’t finish them before expiration. Unnecessary bulk for occasional users.
- Alternative: Smaller bottles from pharmacies or grocery stores—buy only what you’ll realistically use.
Premium Kitchen Items (e.g., All-Clad utensil sets, certain nonstick cookware, high-end toasters) — $50–$500+
- Description: Paying a premium for brand name or large sets where you only use a few pieces. Nonstick coatings wear out faster than stainless or cast iron.
- Alternative: Cuisinart or store-brand options at Costco, individual high-quality pieces from Amazon or Target, or basic stainless/cast iron cookware.
Photo Books and Printing Services — Higher pricing since Shutterfly partnership
- Description: Quality and value complaints increased after the switch. Many find better deals and results elsewhere.
- Alternative: Direct Shutterfly, MPix, Walmart, or other online printers—compare current promotions and reviews.
Certain Disappointing Prepared or Frozen Items (e.g., some pizzas or viral snacks) — Varies
- Description: Recent shopper feedback highlights quality declines (bland taste, poor texture) in specific items like certain frozen pizzas or viral chocolates/ice creams.
- Alternative: Homemade versions, highly reviewed staples you already trust, or Costco food court items for better everyday value.
