Most people think of Costco as one of the toughest retail environments for shoplifters. Between membership requirements, receipt checks, security cameras, and warehouse-style layouts, it hardly seems like an easy target.
Yet theft still happens. Retailers refer to these losses as “shrink,” a category that includes shoplifting, employee theft, fraud, damaged merchandise, and inventory errors. And when theft occurs at warehouse clubs, it tends to involve products with high resale value rather than low-cost impulse items.
Electronics, premium alcohol, luxury foods, over-the-counter medications, beauty products, and other high-demand goods can attract thieves because they are relatively easy to resell and often carry substantial price tags. In many cases, organized retail crime groups target the same products repeatedly.
While Costco experiences lower theft rates than many traditional retailers, some products consistently attract far more attention from thieves than others. Here are the items most likely to disappear from warehouse shelves.
1. High-End Liquor and Wine
One of the first areas loss-prevention employees point to? The liquor section.
Costco is known for selling big-name spirits, whiskey, tequila, and premium wines at lower prices than traditional liquor stores, which draws both loyal members and thieves looking to flip bottles for fast cash. Liquor is easy to resell, doesn’t spoil quickly, and is always in demand, so it consistently appears on lists of commonly stolen retail items.
2. Electronics and Tech Accessories
If there’s one section where the dollar value adds up fast, it’s electronics.
Warehouse clubs secure big-ticket items like TVs, but smaller tech — earbuds, headphones, smartwatches, game consoles, streaming sticks, and routers — are prime targets, along with accessories like chargers, hard drives, and memory cards. These products are small, expensive, and incredibly easy to resell through online marketplaces, which is why electronics show up repeatedly among the most frequently stolen retail categories.
3. Razor Blades and Personal Care
Just like in supermarkets and drugstores, razor cartridges and high-end personal care products are theft magnets in warehouse clubs.
Bulk packs of brand-name razor blades can cost $30–$50 or more, making them attractive to both casual shoplifters and organized retail crime groups. Similar patterns apply to electric toothbrush heads, premium skincare, and salon-brand hair products: they are small, high-value, and easy to flip, which is exactly the profile that shows up in retail theft reports.l
4. Over-the-Counter Medications and Supplements
Over‑the‑counter (OTC) medications and vitamins are a quiet but constant source of loss across retail.
Bulk bottles of pain relievers, allergy meds, heartburn relief, sleep aids, and family-sized multivitamins can run $20–$40 or more in warehouse formats, making them lucrative targets. Industry and security reports highlight OTC medicines, health products, and supplements among the top categories sought by organized retail crime because they’re compact, valuable, and always in demand.nrf+2
5. Meat, Seafood, and High-End Groceries
Costco’s meat and seafood departments are famously popular — and that visibility makes them targets too.
Across the industry, meat, cheese, and seafood regularly appear on lists of the most frequently stolen grocery items, particularly higher-end cuts and branded products. Large trays of steak, ribs, salmon, and shrimp can be worth $50–$100 each, and in some theft rings these bulk food items are resold to smaller stores, restaurants, or through informal markets.
6. Laundry Detergent and Household Essentials
Household staples don’t sound glamorous, but they are a well-documented favorite in organized retail crime.

Surveys and reporting note that laundry detergent has become one of the most stolen products in retail, sometimes even used as a kind of “black market currency.” In a warehouse-club context, bulk jugs of detergent, dishwasher pods, dish soap, trash bags, and paper goods (toilet paper, paper towels) pack a lot of value into a single item and are easy to resell because everyone needs them.
7. Branded Clothing and Shoes
Costco’s clothing section flies under the radar, but apparel is one of the biggest shrink categories across retail.
Retail security resources consistently list clothing, fashion accessories, and footwear among the most commonly stolen items, driven by recognizable brands and easy resale through online platforms. Bulk deals on brand-name jeans, athletic wear, sneakers, and seasonal outerwear give thieves access to valuable labels that can be quickly flipped for cash.
8. Watches, Jewelry, and Small Luxury Items
Many warehouse clubs keep jewelry and luxury pieces behind glass, but that doesn’t eliminate risk.
Loss-prevention commentary notes that display-case items can be vulnerable during busy times, distraction incidents, or when products are being shown to customers. Small, high-value items like watches, gold chains, or designer accessories are easy to conceal and difficult to trace once they leave the store, which is why jewelry is a classic concern in retail security surveys.
9. Gift Cards and Prepaid Products
Gift cards might not look like much, but they’re treated as a major fraud and theft risk in retail.
Law-enforcement and retail-fraud reports describe schemes where criminals tamper with cards on display, swap packaging, or steal activated cards during chaotic moments, then drain balances before victims realize what happened. Because gift cards function like cash once loaded, they are a prime target for both organized retail crime groups and scam operations targeting seniors and other vulnerable shoppers.
How Theft Works in a Membership Warehouse
You’d think the membership model alone would scare off would-be thieves; Costco itself has credited strict entrance control, membership requirements, and exit receipt checks for its unusually low shrink rate, estimated at around 0.11–0.12% of sales.
But theft in a warehouse setting still occurs: some people use borrowed or shared memberships, some work with accomplices to distract staff, and organized groups may hit multiple locations while blending into regular crowds. There’s also the risk of internal theft, which is a factor across the wider retail industry.
Why These Items Keep Getting Hit
The pattern at Costco mirrors broader retail trends: the most targeted products tend to be high-value but relatively small or concealable, easy to resell for cash or online, and often everyday essentials or big-brand items.
National retail surveys estimate that shrink across U.S. retailers reached over $100 billion in losses in 2022, driven heavily by categories like health and beauty, grocery, apparel, electronics, and household goods — all of which have warehouse-club equivalents. That’s why shoppers are seeing more cameras, more locked cases, and slightly more friction when trying to buy certain products.
