Amazon on September 29, 2026, published a preview of the offers for Prime Big Deal Days, the members-only sale that opens at 12:01 a.m. PDT on October 6 and runs for 48 hours. According to Amazon, Prime members in 22 countries can shop millions of offers across fashion, electronics, beauty, toys and groceries, with a fresh batch of limited-quantity deals released at midnight, 8 a.m. and 1 p.m. PDT on each of the two days.
The post devotes a section of its own to Alexa for Shopping, the company's AI shopping assistant. According to Amazon, the assistant shows a product's price history for up to 365 days and places an order automatically once an item reaches a price the shopper has set.
In Short
Amazon listed what it plans to discount during a two-day sale for Prime members on October 6 and 7, and described how its Alexa assistant can watch prices and buy things automatically. The sale reaches Prime members in 22 countries and matters to brands and advertisers, because new offers appear three times a day and some purchases can happen without a shopper ever opening a search page. What changes is the pace and the automation: deals arrive on a fixed daily schedule, and a price chosen in advance can trigger an order by itself.
What Amazon published
Amazon had already set the October 6-7 dates on September 14, fifteen days before the new post, so the September 29 document concerns what will be marked down and not when. The sale follows Prime Day, which Amazon moved into June for 2026 across 26 countries.
The structural feature is the release cadence. Under the Today's Big Deals banner, new offers appear at midnight, 8 a.m. and 1 p.m. PDT, at reductions of up to 55% or more, mostly at what Amazon calls its "lowest prices of the year so far". When the banner debuted for Prime Day 2025, the themed drops went live once a day at midnight PDT. Three windows triple that daily rhythm. According to Amazon, the offers are exclusive to Prime members and available only while supplies last.
Examples in the post range from a $2,000 reduction on a Sony big-screen television to markdowns of up to 50% on K-beauty products from medicube and Dr.Jart+. Amazon also lists premium beauty brands such as Charlotte Tilbury and La Roche-Posay, up to 40% off select top brands, and a seasonal "Top 100+ Fall Favorites" list that features Staub pumpkin cookware and a Ninja Woodfire grill. First Aid Beauty and FAO Schwarz appear as brands new to Amazon.
The itemised offers, by the numbers
The post sorts its itemised offers into seven themed groups. Counting the bullet points yields 41 entries: 35 state a percentage ceiling, five state a dollar figure, and one - a Halloween Top 100+ list - states neither.
| Group | Entries | Highest percentage ceiling |
|---|---|---|
| Home and kitchen | 9 | 40% |
| Fashion and beauty | 8 | 50% |
| Technology | 8 | 60% |
| Halloween | 4 | 40% |
| Toys | 4 | 40% |
| Tailgating and TVs | 3 | 40% |
| Pantry, household and pet | 5 | 35% |
The ceilings cluster. Fifteen of the 35 percentage figures read 40% and 13 read 30%; four sit at 35%, two at 50% and one at 60%. Put differently, 28 of the 35 stop at 30% or 40%, and only three exceed 40%.
The 60% entry names the Echo Dot 2-pack and a Ring Battery Doorbell Plus bundle with Indoor Cam Plus. The two 50% entries cover Zappos styles on Amazon and headphones and earbuds from Bose, soundcore and Beats. Dollar figures take two forms: savings of over $500 on Breville espresso machines and on Nikon and Canon cameras, and starting prices of $5 for Halloween candy, $4 for Amazon Basic Care cold and flu relief and $1 and under for a group of snacks.
Because every figure is a ceiling, the post does not indicate how many items in a group actually reach it.
Alexa for Shopping
Alexa for Shopping, formed on May 13, 2026 by merging Rufus and Alexa+, receives four functions in the post. Shoppers can create Deal Alerts for specific needs, set a target price on an item to be notified when it falls, or switch on Auto-Buy, after which, according to Amazon, Alexa purchases the item automatically at that price. Shoppers can also ask the assistant to "update me when [brand] releases something new" for anyone on a list. Price History, reachable from a product detail page or by asking the assistant, covers up to 365 days. Lists, which can be created for each occasion and shared with family and friends, trigger notifications when listed items drop in price or go on deal.
None of the mechanics is new. Rufus gained automatic purchasing at target prices, price tracking and account memory on November 18, 2025, with a 24-hour free cancellation window on purchases made that way, and a full year of price history followed on May 1, 2026. The September 29 post describes no cancellation terms for Auto-Buy orders placed during the sale.
Auto-Buy hands a purchase decision to agentic AI software that acts inside limits the shopper sets: an item, a price, a moment. What does a sale look like when part of the buying is delegated in advance?
Other programmes, delivery and membership
Offers beyond the main lists
Book offers reach 60% on titles tied to Prime Video productions, among them the Terminal List boxed set and a Stephen King box set featuring Carrie, and 40% on Verity by Colleen Hoover, which is linked to an upcoming Amazon MGM Studios film. Deals from U.S.-based small businesses go to 50% on select products from Barefoot Dreams and Michael Todd Beauty.
Amazon Haul carries penny deals on select items, beauty favorites at up to 50% off, and ongoing reductions of 5% on spending of $50 or more and 10% on $75 or more.
Groceries and fast delivery
Harvest Grocery Deals run to 70% off select items, including organic Honeycrisp apples at $2 per 2-lb bag and proteins under $3, with free Same-Day Delivery on orders over $25. Amazon states that its grocery prices meet or beat those of other major retailers; the post supplies no comparison data.
Amazon Now, the 30-minute service that launched in the United States on May 12 at $3.99 per order for Prime members, offers free delivery on orders over $15 during the event. Listed items include 6 oz of salmon from $3, avocados at $0.33 and baby carrots at $0.50, plus Blink cameras at up to 60% off. In Amazon's words, "Amazon Now is available in select cities."
Membership and geography
Prime costs $14.99 per month or $139 per year in the United States, with a 30-day free trial for eligible customers. Prime for Young Adults, open to higher education students and 18- to 24-year-olds, starts with a six-month free trial and then costs $7.49 per month or $69 per year. Prime Access, for qualifying recipients of government assistance and income-verified customers, costs $6.99 per month after a 30-day free trial.
Members in 22 countries can take part, though Amazon cautions that "dates may vary per country". The post gives no per-country schedule. Were the Pacific timetable applied unchanged in Central European Summer Time, the three daily drops would land at 9 a.m., 5 p.m. and 10 p.m., and the sale would open at 9:01 a.m. on October 6.
Why the sale matters to the marketing community
A calendar that has moved
Prime Big Deal Days began in October 2022 as Amazon's second annual members-only event. The 2024 edition covered 19 countries, the 2025 edition ran on October 7 and 8, and the 2026 edition covers 22, four fewer than June's Prime Day.
For sellers the sequence ran backwards. Deal submission opened on July 8 and closed on September 8, and the main inbound stock cutoff fell on September 16, while the dates themselves were published on September 14. Fees were held at $100 upfront per promotion plus 1.5% of promotional sales, capped at $5,000. On August 31 Amazon added business-only deals with a 15% minimum discount during high velocity events, a category it defines by example as Prime Big Deal Days, Black Friday and Cyber Monday.
What the last event measured
Prime Big Deal Days compresses demand on Amazon's retail media network into 48 hours. Amazon reported advertising services revenue of $19.8 billion for the second quarter, up 26%, with Sponsored Products named as the largest contributor.
The June event offered a measured contrast. CommerceIQ's first-look data showed US advertising spend down 8.8%, product page traffic down 10.3% and unit conversion up 17.1%, with ordered revenue 1.7% below the 2025 event. Brands placed 88% of event ad spend in Sponsored Products, while Sponsored Display spend fell 70%. The report attributed part of the conversion gain to Alexa for Shopping, offering that as a plausible factor and not a proven cause.
A shopper who has delegated a purchase to Auto-Buy does not pass through a search results page at the moment of conversion, which is where sponsored placements sit. Rufus, the assistant that Alexa for Shopping absorbed, already narrows roughly 50 search results to about five named products, and Amazon disclosed with its fourth-quarter results that Rufus generated nearly $12 billion in incremental annualized sales in 2025. How many October orders will bypass a page where a brand has paid to appear? The post offers no figure.
The price of that attention is also contested. The FTC and 22 states sued Amazon on August 31 over what they describe as about $20 billion in hidden advertising surcharges. According to the complaint, Amazon raised its surcharge ceilings around events it internally calls high velocity events, a list that includes Prime Big Deal Days. Amazon rejects the allegations and has not been found liable.
Pricing claims
The phrase "lowest prices of the year so far" carries no stated method, and the post gives no count of the offers that meet it. The baseline has shifted this year: since April 23, 2026, Amazon has required sellers to substantiate list prices with recent sales at that price or third-party retail evidence, and it has said the change aligns the reference price shown across its store with the Price History graph on product pages. The 365-day view that Alexa for Shopping promotes draws on that same record.
Beyond the word "millions", the post offers no deal count, no sales targets and no forecasts.
