September 16, 2026
Are you wondering how Prime Day has transformed the summer sales calendar? In just a few years, Amazon's event has become a major rendezvous that shapes the purchases of millions of consumers, to the point of creating a true summer commercial season.
For an e-commerce merchant, understanding this phenomenon is essential: it is no longer just about reacting to the competition, but anticipating a period when purchase intent is naturally stronger. Consumers compare, look for alternatives, and are ready to spend.
The trap would be to believe that you have to imitate Amazon or Walmart to benefit from it. The reality is more subtle: small and medium-sized shops can stand out by focusing on differentiating strategies, without entering into a price war.
So, how has Prime Day reshaped retail? On the agenda:
Why has Prime Day become an essential rendezvous?
How have Amazon's competitors reacted to this new calendar?
What are the opportunities for independent merchants?
How to prepare your store for this summer season?
What marketing strategy to adopt during this period?
Let's get started.
Summary
Why has Prime Day become an essential event?
Launched in 2015, Prime Day was initially a simple loyalty operation for Amazon Prime members. The idea was to offer time-limited deals during a traditionally slow period for e-commerce. No one imagined then that this event would become a pillar of the commercial calendar.
Eleven years later, the finding is clear: Prime Day has trained consumers to look for summer sales, exactly like Black Friday launches the holiday shopping season. The regularity of the event, combined with massive marketing and deep discounts, has created a shopping reflex that is hard to ignore.
The numbers speak for themselves. In 2025, US e-commerce sales reached $24.1 billion during the event, a 30.3% increase compared to the previous year. Amazon is estimated to have generated around $13 billion over this period, according to several estimates. The event has also lengthened: from 24 hours in 2015, it grew to four days last year.

How has Prime Day changed shopping habits?
The most profound change concerns consumer behavior. Before Prime Day, summer shopping was mainly driven by vacations or the back-to-school season. Now, a growing share of buyers voluntarily postpones their purchases to wait for this promotional period.
This postponement phenomenon is crucial for merchants. It means that sales are not simply displaced: they are concentrated in a very short window. Consumers compare prices, read reviews, and wait for the best moment to take action.
For online stores, this implies rethinking their calendar. Inventories must be prepared, advertising campaigns planned, and teams mobilized well before the start of the event. Failing to anticipate this period means risking missing out on a major peak in purchase intent.
How did Amazon's competitors react?
The clearest proof of Prime Day's influence is the reaction from competitors. Many retailers have copied the model by creating their own summer events. Walmart, for example, scheduled its Walmart Deals promotion to overlap with Prime Day 2026 dates, running from June 22 to 28.
Target followed suit with its Circle Deal Days event, scheduled for June 23 to 26, offering early access for members of its Circle360 program. Best Buy, wholesale clubs, apparel chains, and home improvement stores are also launching similar promotions.
These companies are not just reacting to Amazon. They are responding to consumers who compare products using AI, search engines, marketplaces, brand websites, and social media. The result goes beyond Prime Day: a true summer shopping season has established itself.
What is the impact on the merchants' commercial calendar?
For merchants, this new season has concrete consequences across the entire value chain. Inventory purchases must be anticipated, advertising budgets reserved, and merchandising planned several months in advance. Black Friday requires preparation throughout the autumn; Prime Day now has a similar effect.
Manufacturers time their product launches around the event. Merchants negotiate promotional budgets with their suppliers. Marketing teams book their campaigns for June and July. Even companies that never offer discounts adjust their content calendars and email mailings to take advantage of the surge in shopping.
This summer season is characterized by increased traffic, heightened purchase intent, and concentrated promotional activity. For Shopify stores, this is an opportunity not to be missed, provided they prepare for it correctly.
What are the opportunities for independent merchants?
Amazon captures the lion's share of Prime Day sales, and big retailers like Walmart or Target also benefit. But small and medium-sized shops have real opportunities too. Consumers are "conditioned" to spend and actively search for alternatives and niche products.
The goal is not to compete with Amazon on price, but to benefit from the activity generated by this period. Several approaches work particularly well: offering unique categories that stand out from classic discounts, creating bundles of complementary products that preserve margins and increase the average basket value, or developing exclusive or private-label items that avoid any direct price comparison.
The key is to remain visible when consumers are in buying mode, while presenting an offer that cannot be directly compared to those of the giants.
How to prepare your shop for the summer season?
Preparation begins with the analysis of your past sales data. Which products sell best in June and July? Which categories generate the most margin? This information allows you to anticipate demand and build up appropriate stocks, without overloading your cash flow.
Next, think about your merchandising. Highlight your differentiating products, those that cannot be directly compared to the offers of the giants. Prepare clear category pages and product sheets optimized for conversion. A well-organized store more easily converts traffic into sales.
Finally, anticipate logistics. The summer period generates a peak in orders: check your shipping times, plan appropriate packaging and communicate clearly on your delivery times. A well-informed customer is a customer who completes their purchase with confidence.
What marketing strategy should be adopted during this period?
Marketing is the key element to take advantage of this summer season. Email campaigns, SMS messages, paid advertising on search engines and social networks all benefit from heightened purchasing intent. Now is the time to ramp up your efforts, not reduce them.
Content marketing can also play a major role. Buying guides, comparison articles, and product recommendations attract consumers in the research phase. This content positions you as a reference and captures qualified traffic, ready to discover your brand.
The goal is not to steal Amazon's customers, but to be visible when consumers are in buying mode. This is the opportunity to introduce your brand or product range to buyers who could return for years to come.

How to use bundles to increase the average order value?
Complementary product bundles are a particularly effective strategy during this period. By grouping several items together, you increase the average value of each order while offering a proposition perceived as advantageous by the customer. This is a smart alternative to direct discounts that erode your margins.
To create relevant bundles, analyze your customers' buying habits. Which products are often purchased together? Which combinations meet a specific need? A well-thought-out bundle simplifies the purchase decision and increases customer satisfaction.
This approach is all the more relevant as consumers actively compare offers during the summer season. An exclusive bundle, impossible to find elsewhere, protects you from direct comparison with e-commerce giants. It is a way to increase sales of an e-commerce store without sacrificing your margins.
Why bet on exclusive or private label products?
Exclusive or private label products are an effective shield against price comparison. If your product does not exist anywhere else, the consumer cannot find it cheaper at a competitor. This strategy eliminates the main advantage of large platforms: the lowest price.
Developing a private label requires an initial investment, but the benefits are long-lasting. You control your positioning, your margins, and your image. During the summer season, these products become your best ambassadors: they attract attention without being drowned in the mass of comparable offers.
Consumers are looking for specialized products and unique experiences. By offering a differentiating selection, you meet this need while avoiding a price war. This is a winning strategy for independent merchants who want to stand out during this highly competitive period.
How to integrate Shopify with Amazon to manage this period?
If you sell on both Shopify and Amazon, managing this period can quickly become complex. Inventory, orders, customer reviews: each channel has its specificities. An effective integration allows you to synchronize your data and avoid management errors.
The main challenge is inventory management. During Prime Day, order volumes skyrocket. Without real-time synchronization, you risk selling unavailable products, which generates cancellations and unhappy customers. A robust integration protects your reputation and your revenue.
Customer reviews are also a key element. Consumers consult them massively before buying, especially during promotional periods. Centralizing and displaying these reviews on your Shopify store builds trust and improves your conversion rate. Discover how to integrate Shopify with Amazon for products, inventory, and reviews.
