Recognizing Walmart Unauthorized Charges & Common Scams

Distinguish fraud from errors to avoid unnecessary disputes. 80% of cases involve scams exploiting Walmart's trusted brand.

Signs of Fraud vs. Error:

• Unknown charges post-phishing email/text (urgent links, fake @walmart.com addresses).
• Small "test" charges before big hits.
• Walmart+ renewals you forgot (check app).
• Stats: $1B lost to Walmart impersonation scams (2013-2022, LifeLock); Walmart #1 at 16% of phishing.

Mini Case: Sam's Club $4K fraud--scammers used stolen credentials for Midwest pickup while victim slept in California (HumbleDollar).

Walmart Phishing, Gift Cards & App Charges

Phishing (email/text), vishing (robocalls), smishing dominate. Scammers mimic Walmart for gift card drains or Visa gift card unauthorized deductions.

• Walmart Alerts: Never send gift card PINs/photos--treat as cash. Marketplace fakes surged 900% seller growth (2019-2024).
• Pickup Order Fraud: Scammers order via app, change details for in-store theft.

Walmart+ Membership & Subscription Traps

Unauthorized renewals hit hard. 2022 class actions (TopClassActions/ClassAction.org) alleged misleading "save $1,300+/year" claims vs. actual limits on free delivery/shipping.

• Dispute auto-charges via app or 1-800-966-6546.
• Promised $800+ delivery savings often don't materialize, per suits.
