Amazon extended its Black Friday and Cyber Monday deal sourcing deadline to November 13, according to an October 23 Seller Central update. That is 24 extra days past the October 20 cutoff published in July.

The extension covers deal submission. It does not move FBA inventory cutoffs, waive promotion requirements, or guarantee every seller and ASIN can submit every deal type.

What Amazon Actually Extended

The announcement says the deal sourcing window now runs through November 13, then explains how to create Prime Exclusive Discounts through Advertising, Price Discounts, and the Events menu.

There is an ambiguity worth catching. The notice says deal sourcing remains open, but its specific instructions cover Prime Exclusive Discounts. It does not explicitly confirm Lightning Deals and Best Deals are still available to every eligible seller through November 13.

Your Deals dashboard is the authority. If an ASIN or promotion type does not appear there, a general announcement does not create eligibility for it. Amazon can also flag a deal as suppressed or at risk after submission if the product, price, or account stops meeting requirements.

Two Inventory Doors Already Closed

The July calendar set separate inbound dates alongside the October 20 deal deadline. Amazon's Q4 2026 deadlines put AWD shipments at October 14, FBA shipments using minimal splits at October 21, and FBA shipments using Amazon-optimized splits at October 28.

Amazon's new notice sends sellers back to the existing peak-readiness playbook for inventory cutoffs.

So the promotional door reopened while two inventory doors have closed. October 28 is close enough that a shipment created now has little room for an appointment or receiving delay.

Check sellable FBA units, reserved units, recent receiving times, and the stock needed for the rest of Q4 before submitting anything. A promotion increases order velocity. It cannot make inbound inventory sellable on time.

That matters most for ASINs already running lean. Selling the last available units during Black Friday sacrifices full-price sales later in the season and damages organic placement if the listing goes out of stock.

More Time Does Not Improve the Economics

The extension gives you more time to submit. The deal still has to absorb the discount, referral and fulfillment fees, advertising, returns, and the cost of replacing inventory.

Take a product at $40 with $28 of variable cost before the deal discount. A 20% promotion drops revenue to $32 and leaves $4 before any event fee or increase in ad cost.

The original $12 contribution falls by two-thirds.

The question is how many additional profitable units the event produces. The Q4 promotion calendar covers why a busy sales dashboard can hide weak contribution once discounting and advertising are counted.

Run it at ASIN level with the exact deal price, current fee preview, expected return rate, ad budget, and replenishment cost. If the promotion only works at unusually low ad spend or zero returns, it is not a plan.

What to Check Before November 13

Start in Seller Central rather than a spreadsheet. Confirm the event and promotion type are available for each intended ASIN, then record the displayed price requirement, fee, and status.

Separate inventory into sellable, reserved, and inbound. Do not count a shipment as event inventory until Amazon has received it and units are available for sale. If stock is tight, model the promotion against a daily sales cap and your target post-event inventory position.

Then inspect Account Health, listing status, reference prices, and any deal warnings.

Amazon recommends advertising early so deal ASINs collect traffic and conversion data before the event. That is reasonable, but an early campaign still needs a budget and a stop rule.

The extension is a second chance, not a reason to force every eligible ASIN into the event. Submit only when the dashboard, stock position, and contribution model all agree.
