EU and Portugal Find 30% of Black Friday Retailers Use Fake Discounts

Portuguese and European authorities have uncovered widespread violations during last year's Black Friday and Cyber Monday sales, with nearly one-third of online retailers misrepresenting discounts and more than one-third attempting to add unwanted items to shopping carts.

The coordinated enforcement sweep—involving the Portugal Consumer Authority, 22 other EU member states, Iceland, and Norway—inspected 314 online merchants and documented systematic failures to comply with consumer protection regulations. The findings show that shoppers navigating seasonal sales events encounter widespread issues including misleading pricing, manipulative countdown timers, and hidden fees obscured until checkout.

Key Findings

• 30% of retailers advertised false discounts, potentially inflating "original" prices to exaggerate savings.

• 36% attempted to add optional items to shopping carts, with 40% of those cases lacking clear consent mechanisms.

• 18% used pressure tactics like fake scarcity warnings—more than half of which were misleading or unsubstantiated.

• 10% concealed shipping or service fees until the final checkout stage, in violation of EU transparency requirements.

Discount Misrepresentation

The investigation focused on the two largest online shopping events of the year, when cross-border e-commerce peaks and consumers in Portugal frequently purchase from vendors across the European Union. Authorities assessed whether advertised "deals" complied with the Omnibus Directive, which requires merchants to display the lowest price charged in the prior 30 days when advertising a discount.

The results showed significant non-compliance. Nearly one in three retailers failed to reference prices correctly, a violation that contradicts the fundamental premise of Black Friday as a savings opportunity. In practice, a product advertised at "50% off" may never have been offered at the stated original price, or the "sale" price may match prices charged weeks earlier.

Portugal's Directorate-General for Consumer Protection (DGPC) participated in the sweep as part of the EU-coordinated action and has authority to pursue corrective measures and sanctions against non-compliant vendors operating in Portuguese markets.

Unwanted Cart Additions and Dark Patterns

Beyond pricing issues, the sweep documented a widespread pattern of "dark patterns"—design choices that push users toward unintended actions. More than one-third of inspected sites attempted to add optional items—such as extended warranties, insurance, or accessory bundles—to consumers' carts without explicit, affirmative consent.

Critically, 40% of those cases involved pre-checked boxes or unclear language that did not meet EU standards for informed consent under the Unfair Commercial Practices Directive. For shoppers in Portugal, this means clicking "proceed to checkout" could inadvertently add charges for products never requested, with the burden of identifying and removing unwanted items falling on the buyer.

EU regulations require that any optional purchase must be presented with a clear, separate opt-in mechanism. Vendors failing to comply may face enforcement action, including orders to redesign checkout flows and potential financial penalties.

Pressure Tactics and Manufactured Scarcity

Nearly one in five retailers employed pressure tactics, primarily countdown timers ("Only 2 hours left at this price!") and scarcity warnings ("Only 3 items remaining in stock!"). The sweep found that more than half of these tactics lacked factual basis—timers that reset after expiration, inventory warnings unsupported by actual stock levels, or "limited-time" discounts repeated weekly.

These techniques exploit documented psychological biases, creating artificial urgency that can undermine deliberate purchasing decisions. For consumers in Portugal engaging in cross-border online shopping—which represents a significant segment of e-commerce activity—the risks are compounded: a rushed purchase from a vendor in another EU state can complicate returns and dispute resolution, even under harmonized consumer protection frameworks.

The European Commission has indicated that enforcement of anti-manipulation provisions will strengthen, particularly as digital tools enable more sophisticated personalization of pressure tactics based on browsing behavior and user data.

Fees Not Disclosed Upfront

One in ten inspected retailers concealed mandatory charges—including shipping, payment processing fees, or service charges—until the final checkout stage. This practice conflicts with the Consumer Rights Directive, which mandates that all costs be disclosed upfront, enabling consumers to make informed price comparisons before committing to a purchase.

For residents in Portugal shopping across EU borders, undisclosed fees can be particularly problematic. A product listed at €60 may increase to €75 at checkout due to shipping from another EU country or handling charges never mentioned on the product page. Under EU consumer law, such practices—known as drip pricing—are violations subject to corrective measures and penalties.

What Consumers Should Know

The EU-coordinated sweep's findings will inform enforcement actions in coming months. Retailers identified as non-compliant may face corrective orders, fines, or public identification by national authorities. The European Commission has committed to continuing seasonal enforcement sweeps to ensure compliance as e-commerce expands and sales events extend beyond Black Friday to include Single's Day, Prime Day, and other discount periods.

For consumers in Portugal, the findings underscore that regulatory oversight is active. Consumer protection laws are in place, and enforcement mechanisms exist through national authorities and EU coordination. Understanding your rights—and knowing how to verify pricing claims, review cart contents, and recognize pressure tactics—remains essential for making informed purchasing decisions.

Tips for upcoming sales events:

• Document advertised prices weeks before sales to verify discount authenticity.

• Review your cart thoroughly before proceeding—check for pre-added items you did not select.

• Treat countdown timers and scarcity warnings with skepticism—they are often unverified or recycled across multiple sales periods.

• Verify the total price early—reputable retailers display all charges, including shipping, before requesting payment information.

The sweep demonstrates that regulatory authorities across the EU are actively monitoring e-commerce practices. Compliance is improving through enforcement, but informed consumer behavior remains an important safeguard in online transactions.
