2026 Peak Season Pricing Checklist: Dates and Surcharges

The 2026 Peak Season Pricing Checklist: What Changed

Peak season 2026 does not fall where last year's plan expects it. Cyber Monday is Monday 30 November. Black Friday is Friday 27 November, Thanksgiving is Thursday 26 November, and every one of Cyber Week's five days sits inside November. Those dates are the spine of this checklist.

The reasoning already lives elsewhere on this blog. The Black Friday price monitoring playbook covers why the discount curve starts in October, why stock beats price during Cyber Week, and what the Adobe and DataWeave numbers say about discount timing. This post is the list, not the argument: what to do each month, keyed to the real dates, including three changes copying last year's plan will not catch.

The 2026 Dates, With the Carrier Overlay

Print this one. Most peak-season advice is date-free, which is how sellers prepare against a calendar that has quietly moved.

Date	Event
Mon 28 Sep 2026	FedEx peak surcharges begin
Mon 26 Oct 2026	FedEx full peak surcharge period opens
Wed 11 Nov 2026	Singles Day
Mon 23 Nov 2026	FedEx highest-charge window opens
Thu 26 Nov 2026	US Thanksgiving, Cyber Week begins
Fri 27 Nov 2026	Black Friday
Sat 28 Nov 2026	Small Business Saturday
Mon 30 Nov 2026	Cyber Monday, Cyber Week ends
Tue 1 Dec 2026	Giving Tuesday
Sat 19 Dec 2026	Super Saturday
Fri 25 Dec 2026	Christmas Day
Sat 26 Dec 2026	Boxing Day (UK)
Sun 27 Dec 2026	FedEx highest-charge window closes
Mon 28 Dec 2026	UK substitute bank holiday (England and Wales)
Sun 17 Jan 2027	FedEx peak surcharges end

Thanksgiving to Christmas is 29 days this year against 28 last year, so the December tail has one extra day in it. And if you ship to or from the UK, the Boxing Day window is a three-day block ending on a substitute bank holiday, which means a sale opening on the 26th has three days of orders sitting unshipped until Tuesday the 29th.

Where the Money Actually Landed Last Season

Adobe Analytics reported U.S. online spend of $257.8 billion between 1 November and 31 December 2025, a record, up 6.8% year over year (Adobe, January 2026). Adobe separately put season-to-date spend through Cyber Monday at $137.4 billion, with Cyber Week itself at $44.2 billion (Adobe, December 2025).

Divide one set of figures by the other and the season splits three ways. These shares are arithmetic on Adobe's published totals, not a statistic Adobe published:

Window (2025)	Online spend	Share of season
1 to 26 Nov, before Cyber Week	$93.2bn	36.2%
Cyber Week, 27 Nov to 1 Dec	$44.2bn	17.1%
2 to 31 Dec	$120.4bn	46.7%

Over a third of the season was done before Cyber Week opened, and Cyber Week delivered barely a sixth of it. A plan that switches on in mid-November has already missed the larger window.

September: Recompute the Floor Before You Publish It

Recompute landed cost against the current customs rules. U.S. Customs and Border Protection's interim final rule, published and effective 24 June 2026, indefinitely suspends the de minimis exemption for merchandise arriving through any mode other than the international postal network (Federal Register, June 2026). Entries valued at $800 or less now need formal or informal entry procedures. Sub-$800 inbound parcels therefore carry duties and entry handling that a pre-2025 margin model does not contain. A floor carried forward from last year's spreadsheet is not a floor, it is a guess.

Put the carrier windows in the diary before you promise free shipping. FedEx starts surcharging on 28 September, opens its full peak period on 26 October, and runs its highest-charge window from 23 November to 27 December, with a Ground Residential demand surcharge of $0.50 to $0.80 per package (Supply Chain Dive, July 2026). A threshold modelled on off-peak rates is wrong for every day of the promotional period.

• Week of 1 September: rebuild landed cost per SKU, entry costs included, and set the floor from it. Check how much room that leaves using what you know about price elasticity in your category.
• Week of 7 September: pick the ten to fifty products where you genuinely compete, collect exact competitor URLs down to the variation, and start recording.
• Week of 14 September: re-model the free-shipping threshold and promotional margin at peak-window shipping rates.
• Week of 21 September: check your product pages on a phone. Adobe put smartphones at 56.4% of online holiday transactions in 2025, and 66.5% on Christmas Day (Adobe, January 2026), so an awkward price or stock badge on mobile costs you more than it looks.
• Week of 21 September: check UPS's demand surcharge table. UPS has not announced its 2026 to 2027 peak schedule as of writing, so do not assume last season's dates carry over.
• Monday 28 September: FedEx surcharges begin. Your unit economics change today whether or not you noticed.

October: The Ramp, Plus Two Movable Dates

Amazon has historically run its second Prime event in the first or second week of October, on 7 and 8 October in both 2024 and 2025, and typically announces two to four weeks ahead. As of publication the 2026 dates are unannounced, so build this block around a movable event in the first half of the month. Adobe's holiday forecast floats too: the 2025 edition published on 15 October.

• Week of 5 October: read the first competitor cuts against your September baseline. Who moved first matters more than how deep they went.
• Week of 12 October: sanity-check your volume plan against Adobe's forecast when it publishes, and reserve buffer stock for whichever week Amazon's fall event lands in.
• Week of 19 October: finalize promotional depth per product, with the recomputed floor as a hard stop.
• Monday 26 October: FedEx's full peak surcharge period opens and runs to 17 January 2027. Every shipping assumption from here to mid-January is a peak-rate assumption.

November Before Peak Week: Set the Switches by the 23rd

Configure everything before Thanksgiving. Change a setting mid-event and you cannot tell whether a quiet alert feed means a calm market or a broken threshold.

• Wednesday 11 November: Singles Day, and your first real read on promotional depth this season.
• Week of 16 November: raise alert thresholds for the peak window and tier check frequency, heroes tightest and long tail loosest. The frequency framework and the alert threshold guide apply as written, executed this week rather than improvised later.
• Week of 16 November: freeze the watch list. Anything added after today has no pre-promotional price to compare against.
• Monday 23 November: FedEx's highest-charge window opens, four days before Black Friday. Check that your free-shipping threshold still clears the floor at these rates. If it does not, the threshold moves, not the floor.
• Tuesday 24 to Wednesday 25 November: dry run. Confirm alerts fire and reach a channel someone reads on a holiday weekend.

Peak Week, 26 to 30 November

• Thursday 26, Thanksgiving: watch, do not react. Thursday-evening prices are frequently tests that get pulled.
• Friday 27, Black Friday: respond only to cuts that have held for several hours. A price that recovers quickly was an error or an experiment.
• Saturday 28, Small Business Saturday, and Sunday 29: the quiet middle. Check whether competitors are holding Friday's depth or walking it back.
• Monday 30, Cyber Monday: treat competitor stockouts as the day's primary signal. When everyone is discounting, running out is the only move that genuinely shifts demand to you.

One reporting note, best raised before the numbers arrive. All five Cyber Week days fall in November 2026, whereas in 2025 Cyber Monday fell on 1 December and December absorbed one of the season's heaviest days. December 2026 will look artificially weak year over year, November artificially strong, with no change in underlying demand.

December: Revert First, Then Read the Data

• Tuesday 1 December, Giving Tuesday: revert peak thresholds and frequency to their September values.
• Weeks of 7 and 14 December: run the post-mortem while everyone still remembers. Who moved first, who held, and where you matched a cut you did not need to.
• Saturday 19 December, Super Saturday: the last date where a price change can still influence a gift purchase that ships in time.
• Friday 25 December: no action. Confirm alerts are still delivering to a channel someone reads.
• Saturday 26 to Monday 28 December: UK Boxing Day block, Monday a substitute bank holiday in England and Wales.
• Sunday 27 December: FedEx's highest-charge window closes, so clearance margins improve from here.

January: Returns Are a Pricing Input

Returns change what the season actually earned. The NRF and Happy Returns put returns at 19.3% of online sales, with retailers expecting 17% of holiday sales back, from a survey of 2,006 consumers and 358 ecommerce professionals at merchants above $500 million (NRF, October 2025). Apply that rate to your peak-week revenue before calling a discount depth successful.

• Week of 4 January: recalculate net peak revenue after returns, by product, against the discount depth you ran.
• Week of 11 January: feed the result into next season's floors, and note which competitors reset list prices upward in October so November's discount looked deeper than it was.
• Sunday 17 January 2027: FedEx peak surcharges end.
• Late January: set next season's volume plan against the NRF's forecast of 4.4% U.S. retail sales growth in 2026, to $5.6 trillion (NRF, March 2026), rather than against last season's actuals.

Questions About the 2026 Peak Calendar

Is Cyber Monday 2026 on 1 December?

No. Monday 30 November. Thanksgiving is the fourth Thursday in November, the 26th, and Cyber Monday is the Monday after. Several calendar sites still surface 1 December, which was the 2025 date.

Does the de minimis change affect me if I only sell domestically?

If you import any inventory in parcels valued at $800 or less through a non-postal mode, yes. The rule is about how goods enter the country, not where you sell them.

Should December's weak year-over-year number worry me?

Not on its own. Compare November and December 2026 combined against the same two months in 2025. The month boundary moved, so the split is not comparable, but the total is.

Running a Dated List Without Living in Browser Tabs

A checklist this specific only works if the recording part runs itself. Respot takes a competitor product URL, detects the product details, then tracks price and stock per variation and alerts you when either moves. Per-variation tracking is what makes the peak-week stockout signal usable: a competitor selling out of the one size that competes with your bestseller registers as a real stockout instead of being averaged away at parent-product level.

The free plan covers 5 trackers with 7 days of price history and no credit card, enough to test the September block on your most contested products. Paid tiers run to 100, 400 or 2,000 trackers with longer history and a tighter check floor, which is what matters between 26 and 30 November. Plans and limits show which tier covers your list.

The Two Dates to Put in the Diary Today

Monday 28 September, when FedEx surcharges begin and your unit economics change. And the week of 16 November, when thresholds and frequency get set and the watch list closes.

Do the floor price first, though. It is the only item this year with a legal input that was not there in 2024. Recompute landed cost, set the floor from it, and hang the calendar off a number you can defend. Start recording your competitors' prices while September still counts as early.
