Costco Member Shopping Complaints: How to Submit & Resolve

You’ve just finished a big Costco run, and something doesn’t add up – a price tag that seems odd, a missing aisle sign, or a receipt check that feels intrusive. You’re not alone: thousands of members air similar frustrations on social media each month. This guide walks through every way to submit a complaint to Costco, explains common grievances like price codes and receipt checks, and covers the pending class action lawsuit over tariff surcharges – so you can decide how to proceed.

Gold Star membership fee: $60 annually ·
Customer service phone: 1-800-774-2678 ·
Common complaint topics: 5: price mislabeling, aisle signage, receipt checking, item availability, tariff surcharges

The pattern in these facts: Costco’s official channels are clear, but the gap between what members expect and what they experience on the floor is where most friction lives.

How do I submit a complaint to Costco?

Call Costco Member Services

• Dial Costco’s official member services line at 1-800-774-2678. Representatives are available during warehouse hours.
• Have your membership number and order details ready. The Federal Trade Commission (U.S. consumer protection agency) recommends keeping records of dates, names, and promises made during the call.

Use the Costco mobile app feedback feature

• Open the Costco app, tap Account, then select Feedback. You can attach photos of pricing issues or store conditions.
• The app generates a case number – save it for follow-up.

Complete the online feedback form on Costco.com

• Scroll to the bottom of any Costco.com page and click Feedback. The form allows you to categorize your issue (membership, pricing, store experience, etc.).
• For serious unresolved problems, the Better Business Bureau (nonprofit consumer advocacy group) recommends filing a complaint there after exhausting Costco’s internal channels.

What are some common complaints from Costco members?

Poor aisle signage and store navigation

• Members on Reddit often say finding items is a guessing game. One user wrote: “Never in my life did I think I’d have to do this, but how do I find stuff in this store?”
• Food Republic (food and retail news site) called missing aisle labels one of the top recurring complaints.

Receipt checks at exit and code 99 procedures

• Many members dislike the mandatory receipt scan at the door. Code 99 triggers a manager review of a receipt, which can add five to ten minutes to checkout.
• Food Republic notes that credit card restrictions – historically only Visa was accepted – also frustrate shoppers.

Parking and crowds

• Same Food Republic report flags limited parking and jampacked lots as a frequent annoyance, especially on weekends.
• Gas station hours can differ from warehouse hours, causing confusion about pump access – check individual warehouse pages on Costco’s warehouse locator.

The implication: minor inconveniences compound into major frustrations when the store layout feels like a puzzle without a map.

Is there a class action lawsuit against Costco?

Tariff refund lawsuit filed against Costco

• A class action lawsuit was filed in 2025 alleging Costco improperly collected tariff surcharges from members.
• The lawsuit claims Costco raised prices on goods subject to tariffs, then kept the refunds instead of passing them to customers.

Claims that Costco raised prices then sought tariff refunds

• Legal filings assert Costco failed to disclose that price increases included tariff-related markups.
• Costco has not publicly responded to the allegations; the case remains pending court review.

The pattern: If the court rules against Costco, affected members may be entitled to compensation, but the timeline is uncertain.

Why are people canceling their Costco memberships?

Price increases and tariff surcharges

• Social media posts and forum threads cite rising prices — especially on imported goods — as the number one reason for cancellation.
• Members on Reddit and Twitter report sticker shock on items that jumped in price without notice.

Crowded stores and long checkout lines

• Warehouse congestion, particularly on weekends, drives some members to question whether the savings justify the hassle.
• Self-checkout policies that restrict certain items or require employee assistance add to frustration.

Reduction in product quality or availability

• Some members report that favorite products disappear from shelves, replaced by lower-quality alternatives.
• Item availability varies by location, making repeat shopping trips unpredictable.

What is the .97 rule at Costco?

How to read Costco price tags

• Price tags ending in .97 indicate a clearance item marked down for quick sale.
• An asterisk (*) on the price tag means the item will not be restocked.
• Prices ending in .00 typically signal a manager’s special or a temporary discount.

Meaning of .97, .00, and asterisk codes

• The .97 code is Costco’s way of moving inventory without advertising markdowns broadly.
• Members who spot .97 tags on desired items should buy quickly, as stock may be limited.

What this means: The .97 rule is a hidden savings opportunity — but only if you know to look for it.

Does Costco respond to complaints?

Official Costco customer service channels

• Costco’s Member Services page states it aims to reply to feedback within 48 hours. Phone calls typically receive immediate action; the online form and app feedback generate an automated acknowledgment.
• Each complaint filed via phone or app receives a case number that can be referenced in follow-ups.

Response times and escalation options

• The Federal Trade Commission (U.S. consumer protection agency) advises contacting the business first. If Costco does not resolve the issue, escalate to your state attorney general’s office or the FTC itself.
• The Better Business Bureau (nonprofit consumer advocacy group) also accepts complaints against Costco; filing there creates a public record that can pressure the company to respond.

How does Costco handle product recalls and safety?

Costco’s recall information page

• Costco maintains a dedicated recalls page listing all active product recalls, from food to electronics. Members can search by product name or recall date.

CPSC database

• The U.S. Consumer Product Safety Commission (federal safety regulator) maintains a broader recall database covering all retailers. Cross‑checking with CPSC can uncover recalls Costco has not yet posted.

For items that pose health or safety risks, members should contact Costco’s Member Services immediately and reference the recall notice. The CPSC recommends saving the product’s model number and purchase date.

What is the Costco return policy and why it frustrates members?

Electronics: 90-day limit

• Costco’s return policy states that electronics – including televisions, computers, and tablets – must be returned within 90 days of purchase.
• Members who miss this window are often surprised to learn the item cannot be returned, leading to complaints on social media.

Exceptions for alcohol and cigarettes

• Alcohol and cigarettes cannot be returned in certain jurisdictions due to local laws, per Costco’s policy. This is a recurring point of confusion for members who assume all products carry the unlimited return guarantee.

Membership revocations

• Costco’s membership conditions note the company may revoke membership without cause. Members who return large volumes or dispute policies frequently risk losing their membership – a source of anger in online forums.

For the average member, the choice is clear: use tracked channels (phone or app) for time‑sensitive issues, and document everything. The tariff lawsuit adds a layer of uncertainty, but for now, Costco’s own return and membership policies are the biggest sources of friction. Members who understand the rules – and the limits – can shop with far fewer headaches.
