Prime Big Deal Days returns 6 and 7 October

Amazon has confirmed its autumn Prime event for 6 and 7 October, opening at 12:01 a.m. CET on the sixth, for Prime members in twenty-two countries. Target has put its own Circle Deal Days on the same two days.

The event itself is settled. What is not settled, and what matters more to a European seller this week, is when deals had to be submitted. Amazon’s own announcement names no seller deadline at all, and the dates circulating in trade coverage contradict each other and apply to the United States. If you are selling in Europe and you are working from a date you read somewhere, you are working from something Amazon has not published.

What Amazon has actually confirmed

Amazon’s European newsroom carries four facts and no more. The event runs 6 and 7 October. It starts at 12:01 a.m. CET. It is for Prime members only. And it covers twenty-two countries, named as Australia, Austria, Belgium, Brazil, Canada, Colombia, France, Germany, Ireland, Italy, Japan, Luxembourg, Mexico, the Netherlands, Poland, Portugal, Singapore, Spain, Sweden, Turkey, the United States and the United Kingdom.

That country list is the most useful line on the page, because it is a specification rather than an estimate and it tells you immediately whether the event is yours to plan for. Austria, Belgium, France, Germany, Ireland, Italy, Luxembourg, the Netherlands, Poland, Portugal, Spain, Sweden, Turkey and the United Kingdom are in it. If your catalogue sits in a European market that is not on that list, the event is not a trading event for you, and the only thing to manage is the cross-border demand it pulls from the markets that are.

One clock for twenty-two countries

The start time is published as 12:01 a.m. CET, and that is a single clock for a list of countries spanning most of the world. It is worth spending a minute on, because it decides two operational things.

The first is advertising. If your bids and dayparting are set in local time, the opening hours of the event, which are usually the hours with the sharpest demand, will not land where your schedule expects them in any market outside central Europe. A United Kingdom seller is an hour behind the start, an Irish or Portuguese seller the same, a Polish or Swedish seller aligned, and anyone selling into Turkey or the Americas further out again. Check the daypart, not just the daily budget.

The second is service. A deal that goes live at one minute past midnight in Berlin generates its first questions and pricing errors in the hours when nobody is watching.

The deadline that does not exist for Europe

This is the part to get right, because the week has produced three different answers to one question.

Amazon’s own page publishes no deal submission deadline. EcomCrew reports that the submission deadline was extended to 22 September, and qualifies it: the article frames the immediate decision as one for sellers on Amazon.com. PPC Land, publishing later, prints the window as having opened on 8 July and closed on 8 September. The later account carries the earlier date, which is the wrong way round for a straightforward correction.

So there is no established European seller deadline in any public source, and an operator should not act as though there is one. The practical rule is the boring one: the only deadline that binds you is the one inside your own Seller Central account, and that is where to look before you take a date from anywhere else, including here. If nothing is there, nothing has been asked of you yet.

Why October is a margin decision, not a traffic decision

The instinct with an event like this is to treat it as free demand: Amazon spends the marketing money, shoppers arrive, you take the extra units. For a seller holding inventory in Amazon’s network, the arithmetic is less generous than that, and it turns on where the event sits in the calendar.

Amazon’s own published fee schedule steps monthly storage costs up for the final quarter. On the United Kingdom pricing page, standard-size products are charged £0.76 per cubic foot per month from January to September and £1.51 per cubic foot per month from October to December, so the cost of holding a unit roughly doubles at exactly the point this event runs. That changes what a promotional unit is worth. Selling inventory through at a discount in early October avoids a quarter of the higher rate on anything that shifts. Sending extra inventory in for the event, and not selling it, pays the higher rate on the remainder until it moves.

So the event is best read as an inventory clearance opportunity priced against a storage cost that has just gone up, not as a pure volume play. The seller who wins it is the one who knows which SKUs they want out of the building.

The pricing mechanic worth checking in your own terms

One operational detail sits underneath the event and Amazon’s announcement does not mention it. EcomCrew reports that promotional prices during Prime Big Deal Days are excluded from the 30-day and 60-day lookback windows used to set maximum deal prices for Black Friday Week and Cyber Monday.

If that holds for your marketplace, it removes the trap that catches sellers who discount in October and then find their November reference price has been dragged down with it. It is worth confirming against the deal terms shown in your own account rather than taken on trust, because it is the difference between one discounted weekend and a discounted quarter. The general principle survives whatever the specific terms say: before you set an October price, work out what it does to the highest price you will be allowed to charge in November.

Target on the same two days

Target is running Circle Deal Days on 6 and 7 October as well, open to its free loyalty members, with early access for paid Circle 360 subscribers. That matters mainly to sellers with a United States presence, and the shape is worth noting: Amazon’s event is gated behind a paid membership, Target’s is not.

For the business operator

Check your own account first. Seller Central is the only authoritative source for whether you have a deal window, when it closes, and what the terms are in your marketplace.

Pick the SKUs you want out of the building. Slow-moving stock, ageing inventory and anything bulky is where the storage step-up bites hardest, so those are the units where a discount is cheapest in real terms.

Model November before you price October. Work out the lowest price you can offer in the event without damaging the reference price you need for Black Friday, then decide the discount inside that constraint.

From the consumer’s side

Everything above is the seller’s arithmetic. The shopper’s behaviour is what decides whether that arithmetic pays, and it has changed in ways worth naming.

Start with the gate. This is a members-only event, so the person arriving has already paid for a relationship with the retailer and has been marketed to for a fortnight beforehand. They are not browsing for a product, they are arriving expecting a discount and choosing which discount to take. That is a different shopper from the one who lands on a listing in March, and it favours a clear price cut over a clever product story.

Then the competition. With Target running an open loyalty event on the same two days, the discount a shopper sees is judged next to another discount rather than against the usual price. A reduction that would look generous in isolation can read as ordinary on a weekend when everyone is cutting.

The behaviour that costs the most, though, is the one nobody puts in the plan. A shopper who has learned the promotional calendar waits for it. The purchase you win with a discount on 6 October may be a purchase you would have made at full price in November, which shows up as a strong event and a flat quarter. If you cannot tell those two apart in your own numbers, the honest position is that you do not yet know whether last year’s event made you money.

What is not published

Two gaps are worth naming. Amazon states that more than 200 million paid Prime members have access to its selection, but attaches no date to that figure, so it cannot be placed in time or compared against any earlier count, and it is not usable as evidence of anything about this year. And Amazon has published no European seller deadline, no participation criteria and no deal volume for the event. Until it does, the trade coverage is filling a silence rather than reporting a rule.

The three-line version

If you run the Amazon account. Check Seller Central today for a deal window, pick the stock you want out of the building before the higher fourth-quarter storage rate bites, and model November’s reference price before you set October’s.

If you have just taken on the promotional calendar. Two large retailers now run competing events on identical dates, so the October calendar is no longer one retailer’s to set.

If you sign the budget. This is a margin decision, not a media one. Refuse a discount justified by a worked example built on invented inputs rather than on your own landed cost.
