Costco's 90-Day Return Crackdown: What the 2026 Policy Enforcement Means for You

The "no-questions-asked" return at Costco is effectively over. The cause isn't a policy rewrite, but a piece of hardware: the scanner at the warehouse entrance.

For decades, the return policy was retail folklore. You could return almost anything, anytime. But as of February 2026, members face a new reality at the service counter: strict enforcement of the 90-day window for electronics and a backend system that flags "serial returners" before they even reach the register.

This shift is about data. The mandatory membership scanning implemented earlier this year does more than verify your photo; it links your physical presence to your transaction history and return score before you grab a cart.

If you rely on Costco manager special price adjustment rules or returns to manage your budget, the game has changed.

Key Takeaways

Digital Scanning Links to Returns:** The new entrance scanners connect your visit to your return history, flagging accounts with "rental" behavior instantly. 90-Day Rule is Absolute:** Staff authorization for "manager exceptions" on electronics past 90 days has been revoked in most warehouses. Fraud Costs are Driving This:** Retail return fraud hit $103 billion in 2024 (Appriss Retail), forcing retailers to close loopholes. Pivot to Price Adjustments:** With returns getting harder, the smartest way to save is through automated price protection using tools that scan Costco receipts.

The Digital Gatekeeper

When Costco rolled out mandatory membership scanning at warehouse entrances in late 2025, most assumed it was a simple gate to stop non-members. It is actually a tracking tool. According to reports from The Sunday Guardian on February 16, 2026, this system connects your visit to your permanent purchase and return history.

Previously, you were anonymous until you handed over a card at the register. Now, the system identifies you the moment you walk in. This digital identity layer allows staff to flag specific accounts that exhibit "return abuse" patterns—such as returning more than half of what they buy—before a transaction begins.

Return Score — An internal metric used by retailers to track a customer's frequency of returns against their total spending, used to identify potential fraud or abuse.

For the average shopper, this is invisible. But for those who treat Costco like a rental service, the consequences are real. A new monitoring system specifically looks for "rental" behavior, like buying large-screen TVs before the Super Bowl and returning them on Tuesday. If your account is flagged, return privileges can be suspended regardless of your annual spend.

The 90-Day Hard Stop on Electronics

The policy regarding electronics—televisions, projectors, computers, cameras, and major appliances—has included a 90-day window for years. But enforcement relied on humans. Managers frequently overrode the system to keep members happy.

That discretion is gone. As of mid-February 2026, enforcement is universal. Watcher Guru reports that staff are no longer authorized to make "manager exceptions" for these items past the 90-day mark. This targets the Electronics category specifically, a sector that generated $3 billion in sales last fiscal year but remains highly susceptible to "retail borrowing."

Wardrobing — The practice of purchasing an item (often clothing or electronics) for a specific event or short-term use with the intent to return it for a full refund.

This rigid approach closes the "upgrade loophole," where members would return a year-old laptop to subsidize a new model. If you buy a laptop today, you own it on day 91.

Why Now? The $103 Billion Problem

Costco isn't doing this to be difficult; they are reacting to a hole in the retail economy. Fraudulent returns cost U.S. retailers approximately $103 billion in 2024, according to the 2024 Consumer Returns in the Retail Industry Report released by Appriss Retail and Deloitte.

The rise in specific types of fraud is concerning. "Damaged item" claims—where a buyer returns a broken item claiming it arrived that way—jumped by 158% in 2025 alone. When members abuse the policy, costs rise. Eventually, that impacts membership fees and shelf prices.

Michael Osborne, CEO of Appriss Retail, put it simply: "It is clear why retailers want to limit bad actors that exhibit fraudulent and abusive returns behavior, but the reality is that they are finding stricter returns policies are not reducing the returns fraud they face without data-driven enforcement." (Appriss Retail, 2025).

Shopping in the Data Era

If returns are harder, the strategy must change. You stop relying on returns and start relying on adjustments.

While Costco is cracking down on physical returns, their price adjustment policy remains one of the most generous in retail—if you catch the price drop in time. Costco offers a 30-day window to claim the difference if an item you bought goes on sale. However, this policy relies on the purchase date, not the delivery date for online orders.

Here is where manual tracking fails. Most shoppers don't have time to monitor the price of a blender they bought three weeks ago. This behavior gap is why tools to track Costco price drops and apps that scan Costco receipts are gaining traction. Tools like 'CostPal' and 'Warehouse Runner' have seen a surge in popularity in 2026 because they automate this process, alerting you to automatic Costco savings without the risk of being flagged as a serial returner.

Old School Returns vs. New Digital Enforcement

Feature	The "Old" Costco Experience	The 2026 Enforcement Reality
Entry Process	Flash card to greeter	Mandatory scan links ID to return history
90-Day Electronics Rule	Frequently overridden by managers	Hard stop; system blocks override
Lost Receipts	Lookup used as a courtesy	Lookup used to audit return frequency
Excessive Returns	Rarely penalized	Flagged for "rental behavior" review
Price Adjustments	Manual monitoring required	Automated via third-party apps

The Secret of the .97 and .00 Codes

With returns becoming a riskier proposition for your membership standing, identifying the best price before you buy matters more than ever. The crackdown on returns has actually led to better deals on the floor for observant shoppers.

Returned items that are still sellable often end up back on the floor with a price ending in .00. These are "Manager's Specials"—often the deepest discounts in the building. According to Warehouse Runner (Jan 2026), these markdowns are store-specific and often result from the very returns Costco is trying to limit. Finding a .00 tag is a legitimate way to score a deal without playing games with the return policy.

Frequently Asked Questions

1. Does the strict 90-day return policy apply to all items? No. The strict 90-day enforcement applies specifically to electronics and major appliances, including TVs, computers, tablets, cameras, and white goods. Most other items technically fall under the "Satisfaction Guarantee," though a new return pattern monitoring system now flags accounts that return more than 50% of purchased items regardless of category.

2. Can I use the Costco online price adjustment form for warehouse purchases? Generally, no. The Costco online price adjustment form is reserved for purchases made at Costco.com. For items bought in the warehouse, you typically must visit the membership counter physically. However, third-party apps can now monitor both online and offline receipts to alert you when a trip to the counter is worth your time.

3. Will I be banned for making too many legitimate returns? It is possible. While Costco does not publish a specific number, the new digital tracking system identifies "abusive" patterns. If your return history reflects "rental" behavior (buying and returning items for short-term use) or exceeds 50% of your total purchases, your membership may be flagged for review or cancellation. According to the National Retail Federation (2025), 60% of retailers now use tracking data to identify "wardrobing" abuse.

4. How do I get a price adjustment if I lost my receipt? Costco's digital app now stores all historical receipts, which staff can access to process a price adjustment. However, reliance on this digital history is what allows the new system to track your behavior so closely. Using an automated tool to scan Costco receipts ensures you have your own independent record for claims.
