Sweden's Fake-Discount Rules Ahead of Black Friday (CU5): How the 30-Day Lowest Price Law Works

As Swedish retailers launch their November "Black Month", "Singles Day", "Black Week", and "Black Friday" promotional campaigns, the Swedish Parliament's Civil Affairs Committee (Civilutskottet) has issued its latest legislative review of retail discount regulations in Betänkande 2026/27:CU5 (Ändring i reglerna om information vid prissänkningar).

For international residents furnishing an apartment, buying winter clothing, or shopping for electronics in Sweden, understanding how the Swedish Price Information Act (Prisinformationslagen 2004:347) works can save thousands of kronor. Despite strict statutory rules introduced to implement the European Union's Omnibus Directive, audits by the Swedish Consumer Agency (Konsumentverket) and independent price trackers show that a significant share of Swedish e-commerce retailers still use artificial price hikes ("yo-yo pricing") or misleading reference prices in October to make November discounts look far larger than they really are.

This guide breaks down what the Riksdag decided in Betänkande 2026/27:CU5, how the mandatory 30-day lowest price rule operates, which legal loopholes still exist around loyalty clubs and product bundles, and how you can enforce your consumer rights when shopping online or in stores across Sweden.

1. What Is the 30-Day Lowest Price Law (Prisinformationslagen Section 7a)?

Before Sweden updated the Price Information Act (Prisinformationslagen 2004:347) by adding Section 7a, a common retail tactic across electronics, home appliances, furniture, and fashion was simple: raise the price of a popular item from 5,000 SEK to 7,990 SEK for one or two weeks in mid-October, and then drop it back to 4,990 SEK on Black Friday while advertising a massive "Save 3,000 SEK (-38%)!" banner.

Section 7a of Prisinformationslagen makes that practice illegal. Under the statute, whenever a business markets a specific product to consumers with an announcement of a price reduction, two strict rules apply:

1. Mandatory Prior Lowest Price Disclosure: The retailer must clearly state the lowest price it applied for that product during the last 30 days before the price reduction began (often labeled on Swedish websites as "Lägsta pris senaste 30 dagarna").
2. Honest Percentage Math: According to binding precedents clarified by the EU Court of Justice (Case C-330/23) and enforced by Konsumentverket, any percentage reduction, kronor savings figure, or strikethrough price shown in the advertisement must be based directly on that 30-day lowest price.

Look at how the math works in practice under Swedish law:

2. What Did the Riksdag Review in Betänkande 2026/27:CU5?

In Betänkande 2026/27:CU5 (Ändring i reglerna om information vid prissänkningar), the Riksdag's Civil Affairs Committee (Civilutskottet) examined legislative proposals and parliamentary motions regarding how Section 7a of Prisinformationslagen and the Marketing Act (Marknadsföringslagen 2008:486) operate in the Swedish retail market.

During committee deliberations, retail industry groups and parliamentary motions raised questions about three recurring friction points:

• Progressive Discounts (Stegvisa prissänkningar): Under the second paragraph of Section 7a, if a price is lowered gradually without interruption during a single campaign (for instance, an autumn clearance that moves from 20% off to 30% off and then 50% off), the retailer is permitted to keep showing the lowest price from the 30 days prior to the first markdown. However, if the retailer raises the price even for a single day between campaigns - such as raising prices after a "Mid-Season Sale" before launching "Black Week" - the chain is broken, and the lower sale price becomes the new 30-day baseline.
• Perishable and Short-Expiry Goods (Snabbt försämrade varor): Goods that deteriorate rapidly or approach their expiration date - such as fresh groceries, meat, dairy, and cut flowers at ICA, Coop, Willys, or Lidl - are exempt from the 30-day price history requirement so supermarkets can mark down short-dated food by 30% or 50% without administrative barriers.
• General Price Comparisons vs. Price Reductions: The committee reaffirmed that retailers cannot bypass Section 7a simply by replacing the word "Rea" (Sale) with phrases like "Kampanjpris" (Campaign price), "Specialpris", "Black Week-erbjudande", or red price badges. Any visual or textual cue that gives the average consumer the impression that the store has lowered its own price triggers the mandatory 30-day disclosure rule.

3. Five Legal Grey Areas and Retail Tricks Expats Should Watch Out For

Even with strict enforcement by the Consumer Ombudsman (Konsumentombudsmannen, KO), sophisticated retailers use alternative promotional mechanics that either sit outside Section 7a or exploit consumer inattention. When shopping in Sweden this autumn and winter, watch out for these five tactics:

1. The "31-Day Wait" Price Reset

Because the statutory lookback window is exactly 30 calendar days, many electronics and home-goods chains raise their prices around October 15 to October 20 - more than 30 days before Black Friday at the end of November. By waiting 31 to 35 days at the inflated price, the store legally resets its "30-day lowest price" to the higher figure just in time for Black Friday. The only way to beat this legal maneuver is to check a 90-day or 12-month price chart on an independent comparison platform.

2. Loyalty Club Exclusives ("Medlemspris" / "Klubbpris")

Under Swedish and European consumer law guidelines, personalized loyalty vouchers or promotions restricted exclusively to registered members of a customer club (such as Klubbpris or Medlemspris) can in certain structures be treated as conditional loyalty benefits rather than general public price reductions. However, if anyone can join the loyalty club at checkout in seconds and the "member price" is advertised broadly as the main headline price on the product page, Konsumentverket treats it as a general price reduction that must follow the 30-day rule.

3. Multi-Buy and Bundle Deals ("Köp 3 betala för 2" / Paketpris)

Conditional volume offers - such as "3 for 2" (Tag 3 betala för 2), "Buy a phone and get headphones included", or "20% off when you spend over 1,000 SEK" - do not lower the unit price of a single standalone item and therefore do not always display a 30-day unit reference price. Always verify the standalone unit price at competing retailers before assuming a bundle is a bargain.

4. "Rekommenderat Pris" (Manufacturer Recommended Price)

Some online stores display a strikethrough price labeled "Rek. pris" (Recommended retail price) or "Jämförpris" (Comparison price) that the manufacturer set years ago when the product first launched, even though no Swedish retailer actually sells the product at that price today. Under the Marketing Act (Marknadsföringslagen), a recommended price comparison is unlawful and misleading unless the manufacturer's recommended price is genuinely and widely charged across the Swedish market at that time.

5. Special "Black Friday Edition" Model Numbers

In televisions, laptops, robot vacuums, and kitchen appliances, manufacturers frequently produce slightly modified model variants (changing a single letter at the end of the SKU code) exclusively for November sales. Because the SKU is technically "new" or only sold for a brief window at a high launch price in early autumn, it lacks a transparent long-term price history.

4. How to Verify Real Prices and Enforce Your Consumer Rights in Sweden

Sweden has one of the world's most transparent digital price ecosystems. Before making any major purchase during autumn or winter sales, use this four-step consumer verification checklist:

• Step 1: Check the 12-Month Price History on Prisjakt or Pricerunner: Copy the exact product model number into Prisjakt.nu or Pricerunner.se and open the Prishistorik (Price History) tab. Set the view to 6 months or 1 year. You will immediately see whether the store hiked its price in October and whether the product was actually cheaper during summer sales (Sommarrea) or September campaigns.
• Step 2: Inspect the Fine Print Below the Price Tag: Look for the mandatory line "Lägsta pris de senaste 30 dagarna: X kr". If a store displays a "-40%" badge calculated against an "Ordinarie pris" (Regular price) of 10,000 SEK while the fine print admits the 30-day lowest price was 6,500 SEK, the advertisement violates Section 7a of Prisinformationslagen.
• Step 3: Use Your 14-Day Distance Cooling-Off Right (Ångerrätt): Under the Distance and Off-Premises Contracts Act (Lag 2005:59 om distansavtal och avtal utanför affärslokaler), when you buy almost any non-custom physical product online in Sweden, you have an unconditional legal right to cancel the purchase within 14 calendar days from the day you receive the item, even if it was bought on Black Friday clearance. Note that for in-store physical retail purchases, öppet köp (open return) is voluntary, and many physical stores disable voluntary returns on clearance items.
• Step 4: Remember Your 3-Year Statutory Warranty (Reklamationsrätt): Under the Consumer Sales Act (Konsumentköplagen 2022:260), discounted and clearance products carry the exact same 3-year statutory right to complain about original defects (reklamationsrätt) as full-price goods (unless you bought a specific second-hand or floor-display item where a specific scratch or flaw was explicitly disclosed before purchase). Furthermore, for the first 2 years after delivery, the burden of proof rests on the seller to prove that a defect was not original.

5. How Konsumentverket and the Consumer Ombudsman Penalize Violators

Since Section 7a took effect, the Swedish Consumer Agency (Konsumentverket) has conducted automated web-scraping sweeps tracking tens of thousands of products across hundreds of Swedish e-commerce sites during October, November, and December.

When Konsumentverket identifies systematic violations - such as omitting the 30-day lowest price, hiding it behind a tiny tooltip, or calculating discount percentages from a higher "regular price" instead of the 30-day baseline - the Consumer Ombudsman (Konsumentombudsmannen, KO) can either issue a conditional fine injunction (förbud vid vite) or sue the retailer in the Patent and Market Court (Patent- och marknadsdomstolen). Under Section 29 of the Marketing Act, the court can impose a direct market disruption fine (marknadsstörningsavgift) of up to 4% of the trader's annual turnover in the preceding financial year.
