Amazon’s Holiday Beauty Event runs October 19 through November 1 with flash deals reaching 40% off, above the 30% headline. The dates matter more than the discounts.

Black Friday Week and Cyber Monday deal submissions close October 20, the second day of the beauty sale. FBA inbound deadlines for that event fall October 21 for minimal splits and October 28 for Amazon-optimized splits. Both sit inside the beauty event window.

If you sell beauty, the two-week discount environment overlaps every operational deadline that determines your Black Friday participation.

The Deal Economics You Already Committed To

Amazon’s 2026 holiday promotion fees run $100 upfront per promotion plus a variable fee of 1.5% of promotional sales, capped at $5,000. Those are the same rates as Prime Day, with no new eligibility requirements.

Peak fulfillment fees started October 15, roughly $0.32 per unit above non-peak rates, running through January 14. The entire beauty event sits inside that window.

So a discounted beauty unit shipping this week carries the discount, the deal fee, and the peak surcharge simultaneously. The Q4 fee calendar lays out the full stack.

One useful detail if you ran Prime Big Deal Days deals: Amazon excluded those promotional prices from the 30-day and 60-day lookback windows used to calculate maximum deal prices for Black Friday Week and Cyber Monday. Amazon has not published whether beauty event pricing receives the same treatment.

That gap is worth resolving before you set a Black Friday deal price. A beauty event discount that counts toward your lookback could cap your November deal lower than you planned.

Amazon Hasn’t Said Who Supplies the Flash Deals

The beauty event announcement is silent on whether flash deals come from Amazon’s first-party inventory, third-party sellers, or both.

That matters for reading the competitive picture. If the 40% makeup window is primarily 1P inventory, third-party sellers are competing against Amazon’s own margin structure rather than another seller’s.

The named deals skew prestige: Charlotte Tilbury, Lancôme, Dyson, Kiehl’s, Armani Beauty, ELEMIS, at 20-31% off. Mass brands like Pantene, Dove, and Olay appear at 20-39%.

A mid-tier seller sits between discounted prestige and discounted mass for two weeks.

The Flash Calendar Tells You When Pressure Peaks

The rotation runs by category: Makeup October 19-20, Fragrance October 21-22, Health and Wellness October 23-24, Men’s Grooming October 25-26, Skin Care October 27-28, Hair Care October 29-30, Personal Care October 31 through November 1.

Each window concentrates discounting in one category for 48 hours at ceilings of 35% or 40%, above the event’s 30% headline.

If you sell skin care, October 27 and 28 is your pressure point whether or not your products are in the event. Track conversion by day against that calendar. A drop during your category’s flash window tells you something specific about price sensitivity that a monthly sales report will not.

What to Do This Week

October 20 is the Black Friday Week and Cyber Monday deal submission deadline. If you have not submitted, that window closes today.

Check your Deals dashboard for per-deal cutoffs on your account rather than relying on the published date. Some cutoffs run shorter than the general window.

Then confirm your inbound plan against October 21 and October 28. Missing an FBA inbound deadline removes the deal from consideration regardless of whether the submission went through.

For the beauty event itself, the actionable work is observational. Document which of your categories saw volume shifts during their flash window, and whether competing listings held price or followed the discount. That record is what makes next July’s submission decision something other than guesswork.
