Black Friday is 27 November 2026. Cyber Monday is 30 November.
Your inventory decisions are largely made by now. Amazon's inbound deadlines for the event fell on 14 October for AWD, 21 October for FBA with minimal shipment splits and 28 October for FBA with Amazon-optimised splits, with the UK and EU reported on different dates. Check your own marketplace in Seller Central, because these come from seller guides rather than from Amazon directly, and Amazon had not published its Black Friday Week window at the time of writing.
Images are the exception. Nothing gates them. You can change a listing photo on 26 November if you want to. That freedom is the problem, because the worst time to change a main image is the week it has to work hardest.
What changes during a sale event
The product does not change. The competition around it does.
Search results get denser. Categories that normally show you a handful of serious competitors fill up with sellers who only turn up for Q4, every one of them discounted, every one of them in the same grid as you. A shopper scrolling that grid decides fast, at thumbnail size, with a price underneath.
Two consequences follow.
The first is that your main image is doing more work than it does in March, and doing it against more rivals. Marginal differences that cost you nothing in a quiet month cost you position in a crowded one.
The second is that price stops being a differentiator. When everything on the page is discounted, a discount is the baseline rather than the reason to click. What separates two similar products at similar prices is which one looks like it was made by a company that knows what it is doing.
The risk nobody plans for
Amazon checks main images automatically. Background colour and frame fill are sampled rather than judged, and a main image that fails can get the listing suppressed. Suppression takes the listing out of search.
That is survivable in October. In the last week of November it is the whole quarter.
So the real deadline on images is not Amazon's. It is yours, and it is the point after which you no longer have time to recover from a change that goes wrong. Reinstatement is not instant, and support queues are at their longest during peak.
My working rule is to make image changes by 13 November, two weeks out. That is not an Amazon policy and you will not find it in Seller Central. It is the amount of slack I would want to notice a suppression, fix the file and get the listing back before the traffic arrives. If your category is slow to review, give yourself longer.
After that date, leave the images alone unless something is broken.
What to fix, in priority order
You have a few weeks. Spend them in this order.
- Anything currently non-compliant. A main image on an off-white background or with the product filling too little of the frame is a suppression waiting for a bad moment. Fix these first, whatever else is on the list. The rules are in our guide to Amazon product image requirements.
- The main image on your best sellers. Not every listing. The handful that carry the quarter. A sharper, better-framed main image on five listings beats a mediocre refresh across fifty.
- The first gallery image. It is the one most shoppers see after the main one, and on mobile it is often visible without a tap. If it is currently a second angle on white, it is wasted. Make it the shot that answers the question a buyer has: how big is it, what is in the box, what does it look like in use.
- Scale. The single most common reason for a Q4 return is that the thing arrived smaller than the buyer pictured. A shot with a recognisable object for scale, or the product held, prevents a return and a one-star review in January.
What to leave alone
- Listings that are already working. If a product converts well and the images are compliant, a refresh before peak is a risk with no upside. Novelty is not an improvement.
- Infographic overlays on the main image. Still prohibited, still tempting, still gets listings suppressed in the week you can least afford it.
- Anything that needs a reshoot you cannot finish by mid-November. A plan that depends on a photographer having a free Tuesday in late November is not a plan.
If you are reading this in late November
Then the advice is different and it is short. Check your main images are compliant and change nothing else. The gain from a better photo at that point is smaller than the loss from a suppressed listing, and the arithmetic is not close.
Doing it in the time you have
The bottleneck in all of this is rarely knowing what to fix. It is that recutting the main images across even twenty listings is a week of mechanical work, and that week is one you do not have in late October.
That is what Instant Studio is for. One photo of the product goes in, and a set of shots comes back cut out, composited on true white, framed to the fill requirement and sized for the marketplace. It turns the job above from a reshoot into an afternoon, which is the difference between doing it before the 13 November cutoff and deciding to leave it until next year.
Sources
Event dates follow from the calendar: US Thanksgiving falls on 26 November 2026, putting Black Friday on the 27th and Cyber Monday on the 30th. The inbound deadlines are those reported consistently across seller guides citing Amazon's July 2026 Seller Forums announcement, and at least one guide reports different dates for the UK and EU. Amazon's own calendar in Seller Central is the only authoritative source, and the 13 November image cutoff is our reasoning rather than an Amazon rule.
