As a devoted Costco shopper, I enjoy more than just wandering the aisles — I love finding genuine ways to save money at checkout. If you follow me on Flipboard, you already know I collect and share helpful Costco tips worth your time.
Over the years I’ve read many “Costco hack” lists. A lot repeat the same basic advice: read the price tags, buy rotisserie chicken, and shop on weekdays. If you subscribe to our newsletter, you’ve likely seen those pointers. But some popular Costco hacks are outdated or simply incorrect. Store policies change, product programs evolve, and social media myths circulate — so before your next warehouse trip, here are Costco hacks that don’t actually work.
12 Costco Hacks That Don’t Work
Using Instacart
Using Instacart for Costco can save time, but it won’t save you money. Instacart typically charges higher prices than the warehouse, plus service and delivery fees. Because a shopper purchases the items inside the store on your behalf, those added costs are passed to you. If your priority is savings rather than convenience, shopping in-store is usually cheaper.
You Can Shop at Costco Without a Card
A viral TikTok suggested you can enter and buy at Costco using gift cards without a membership. That’s not accurate. Associates confirm the method doesn’t work, and Costco has addressed this misconception. If you don’t have a membership, purchasing a gift card at the door will not let you shop freely inside.
Overstocking on “Death Star” Items
Buying in bulk is a core Costco advantage, but bulk buying only saves money if you actually use the items. Purchasing extras that spoil or sit unused wastes money. Also, some fan-favorite items rotate seasonally or return after a hiatus; items that seem gone for good may reappear. Track seasonal patterns before overstocking.
Skipping the Cart
The idea that carrying items limits impulse buying can work at small grocery stores, but it’s impractical at Costco. Most items are oversized, and carrying them becomes unrealistic. Instead, make a clear list before you go and stick to it — that strategy is far more effective than forgoing a cart.
Clip Coupons
You won’t find many traditional coupons to clip at Costco. The retailer’s deals show up as weekly or monthly sales, not paper coupons. It’s worthwhile to review the current sale rounds before visiting, but collecting coupons isn’t a reliable savings strategy at Costco today.
Use the Costco App
The app has benefits — mainly storing your membership card and receipts — but many shoppers find the website easier to navigate for browsing and online purchases. Costco’s online grocery offerings have been limited compared with other retailers, and the app’s functionality remains relatively basic. Use the app for membership and quick reference, but rely on the website for easier browsing when shopping online.
Listen for the Bell That Signals Rotisserie Chickens Are Done
Yes, the ovens do signal when chickens finish, but the bell is only audible nearby and can be drowned out by a busy warehouse. A more reliable method is to check the oven timers directly or set a reminder on your phone or watch so you return just after cooking finishes.
Buy It Even If You Don’t Need It
Impulse buying because something looks like a good deal is a fast way to waste money. Even items with long shelf life require storage space and eventual use. Don’t purchase a product just because it’s discounted; buy it only if it fits your needs and lifestyle.
Don’t Wait For Seasonal Pies
Costco often offers seasonal bakery items, and while you can freeze products like pumpkin pie for later, there’s no need to hoard them weeks in advance. Many warehouses now use demand forecasting tools in bakeries to manage inventory, so panic buying isn’t necessary.
Book Deals
Costco used to carry books year-round at competitive prices, but the retailer adjusted that strategy and now sells books more seasonally. If you rely on Costco for book purchases, check current availability and timing before assuming they’ll be stocked year-round.
Don’t Shop the Center Aisles
The center aisles often contain strong deals — gift cards, seasonal items, clothing, and special finds. Dismissing the center aisles outright means missing potential savings and unique products. Walk the whole store and keep an eye out for rotating deals in the middle sections.
Shop at Costco on Tuesday Afternoons
Some sources claim 1–4 p.m. on Tuesdays is the ideal shopping window, but our experience differs. The store is typically least crowded right when it opens, and the busiest times are weekend afternoons and weekday evenings around 4–6 p.m. If mornings don’t fit your schedule, try shopping an hour before closing for a quieter visit.
