Amazon's Prime Day 2025 concluded last week, marking its longest duration yet, spanning four days from July 8 to July 11. The extended event was positioned by Amazon as another record-breaking success, with early industry reports acknowledging its expanded sales footprint.
However, for pricing teams and retail analysts, the true measure of Prime Day's impact extends beyond initial headlines. This year's event prompts a deeper inquiry into the actual efficacy of advertised deals, the strategic pricing maneuvers employed by Amazon, the reactive dynamics among European competitors, and the growing legal scrutiny facing promotional pricing practices. This post will dissect these key points to provide a more comprehensive understanding of Prime Day 2025's impact on retailers.
Despite Amazon's declaration of Prime Day 2025 as a "record-breaking event", as was anticipated given its extension to four days, the company refrained from releasing a crucial metric: the total number of items sold. In prior years, Amazon publicly shared these figures, reporting over 375 million items sold in 2023, 300 million in 2022, and 250 million in 2021. No comparable statement was released for the most recent event.
This decision to withhold an important KPI has drawn attention from across the industry. Experts offer a nuanced perspective on the "record sales" claims. Such record sales were entirely anticipated given the extended four-day format, with experts noting that "Anything else would be a big disappointment." Early data initially indicated a 41% decrease in Amazon sales on the first day compared to 2024's opening day, though later analysis predicted a 4.9% total sales growth for the expanded event compared to the combined 2024 Prime Day and subsequent two days. While the extension did result in greater total sales volume, it paradoxically led to lower daily average sales compared to the previous year, notably benefiting Amazon by expanding opportunities for advertising revenue.
For analysts and observers who traditionally rely on such data to gauge the event's actual success against its public communication, this opacity fuels a critical question: if a fundamental sales metric is being guarded, how truly impactful were the advertised deals? Ultimately, for Amazon, the underlying success of Prime Day is measured less by specific item counts and more by its capacity to onboard new Prime subscribers or enhance the shopping engagement of its existing subscriber base.
With a global Prime membership exceeding 200 million, Amazon's influence during Prime Day is substantial, positioning it as an important event for both consumers and competitive retailers. Our analysis of the European market provides several insights into the pricing strategies employed.
Here is a breakdown of market insights and Omnia-exclusive data directly for our data team:

While Amazon's advertised discounts projected substantial savings, proprietary data from the data team at Omnia Retail shows an interesting pre-event pricing dynamic that offers deeper insight into the actual depth of these deals. Our analysis of average price trends leading up to Prime Day 2025 (based on a 3-day rolling average) illustrates a distinct pattern:
A closer examination of the price trajectory indicates an increase in the average price of products in the weeks preceding Prime Day. Our data shows:
Further granular analysis of percentage changes reinforces this perspective:
This data suggests that for a substantial segment of products, the "Prime Day deals" did not always represent significant discounts from the immediate pre-event price. Instead, a considerable number of items either saw their prices return to previously observed levels or experienced only marginal reductions from a recently adjusted base. This sophisticated pricing strategy allows Amazon to promote compelling discounts while diligently managing overall profitability.
Amazon's large-scale sales events invariably create significant ripple effects across the broader e-commerce ecosystem. We analyzed the responsive pricing strategies of key European retailers and marketplaces, MediaMarkt, bol.com, and Coolblue, during Prime Day. Their reactions highlight the intense competitive pressures prevalent in the European market:
Our data indicates varied competitive behaviors:
The diverse responses from these major European players underscore that while Amazon often sets the pace, regional competitors are actively engaged, deploying tailored strategies to retain market share and capitalize on heightened consumer buying intent.
Beyond market dynamics and competitor reactions, a critical legal dimension has gained prominence for promotional pricing within Europe, particularly relevant to Prime Day 2025. This concerns the EU's Omnibus Directive, which mandates transparency in price reductions. Our CEO, Sander Roose, recently highlighted how Amazon's Prime Day promotion communication, when using the manufacturer's Recommended Retail Price (RRP) as a "from price" for discount calculations, may not fully align with the Directive’s requirement that advertised discounts must reference the retailer's own lowest price offered for that product in the preceding 30 days.
Our data, for instance, showed instances where Amazon’s actual discount from its recent selling price was significantly less than implied by RRP comparisons.
Adding significant weight to this discussion, a Munich court recently ruled that Amazon's Prime Deal Days discounts violated the EU Price Indication Directive, specifically finding that discounts benchmarked against MSRP rather than the 30-day lowest price were non-compliant.
This resulted in a public reprimand, with future violations potentially incurring fines of up to €250,000. This ruling serves as a stark reminder for every brand and marketplace seller operating within the EU that regulatory authorities are actively monitoring compliance across the retail sector.
At Omnia Retail, we anticipated these enforcement trends. Our Dynamic Pricing suite now incorporates a "30-Day Lowest Price" dashboard, which displays the lowest price reached per SKU in the past month alongside current and planned promotions. This functionality empowers teams to:
Maintaining transparent pricing is not only crucial for building consumer trust but also for safeguarding margins against potentially significant and avoidable regulatory fines.
Prime Day 2025 reinforces important lessons for the retail sector. Amazon's decision to withhold specific sales metrics, coupled with our data showing prices often reset to prior levels rather than deep discounts, reveals sophisticated promotional tactics. Meanwhile, European competitors aggressively challenged Amazon, often with targeted deals on specific products.
An important development for pricing professionals is the heightened regulatory scrutiny, highlighted by the recent Munich court ruling on the Omnibus Directive. This event underscores the urgent need for retailers to not only optimize pricing for market competitiveness but also to ensure strict adherence to promotional regulations. In today's e-commerce environment, integrating precise, data-driven pricing strategies with robust compliance measures is no longer optional; it is fundamental for growth and maintaining consumer trust.
