1. Why Q4 Decides Everything
The numbers are clear: for most Amazon sellers, Q4 accounts for 40 to 60 percent of annual revenue. October, November, and December are the three highest-grossing months -- and the gap to the rest of the year is enormous.
It is not just Christmas. Amazon has systematically packed Q4 with sales events over the years: Prime Big Deal Days in October, Black Friday and Cyber Monday in November, last-minute gifts in December. Each event brings a massive traffic spike -- and an opportunity you either seize or miss.
What this means for your repricing: the rules that work the rest of the year only partially apply in Q4. Demand explodes, inventory levels fluctuate, competitors behave irrationally, and the BuyBox changes hands faster than at any other time of year.
If you run Q4 with the same min prices, max prices, and strategies as July, you are leaving money on the table. Period.

2. Q4 Calendar 2026: The Key Dates
So you do not miss anything, here are the critical dates for Q4 2026:
October: - Prime Big Deal Days (expected October 8-9, 2026): Amazon's second Prime event. Part of the calendar since 2023. High traffic, aggressive deals, but shorter duration than Black Friday.
November: - Black Friday (November 27, 2026): The biggest sales day of the year. Amazon typically starts its deals week the Monday before. - Cyber Monday (November 30, 2026): Immediately following. For many categories, even stronger in revenue than Black Friday itself.
December: - Holiday shopping (December 1-23): Consistently high demand, especially in the second half of December. - FBA cutoff (approx. December 15-17): Last date by which FBA shipments are guaranteed to be received before Christmas. After this, you work exclusively with inventory already in FBA warehouses. - Last-minute buyers (December 18-23): Shoppers who have not bought yet are willing to pay more. Price sensitivity drops significantly.
January 2027: - Post-holiday selloff (from December 26): Returns increase, demand drops, long-term storage fees loom.
Your repricing must align with these dates -- not with a fixed annual plan.

3. Pre-Q4 Repricing Strategy: September Preparation
If you start in October, you are too late. The most important phase for your Q4 repricing is September. This is where you lay the groundwork.
Build Inventory
Repricing does you no good if you are out of stock on Black Friday. Analyze your sales data from Q4 2025 and reorder early enough. Plan for 2-3x higher sales volume compared to normal months -- for top sellers, even more.
Watch FBA storage limits: Amazon adjusts these before Q4, and if you ship too late, your inventory will not be received in time.
Review and Adjust Min Prices
Your summer min prices are probably too conservative for Q4. Check every product:
- Has your purchase price changed? Did you reorder at a lower cost?
- Have FBA fees changed?
- Can you lower your min price slightly to be more competitive in the BuyBox rotation?
This does not mean selling below cost. But a min price that is 2 EUR lower can make the difference between winning the BuyBox and landing on page 2 during the hot phase.
Prepare Repricing Strategies
For your key products, decide in September which repricing strategy you will run in Q4. Create separate profiles or price groups for:
- Aggressive products: High competition, goal is maximum volume (e.g., JUMP or STEP strategy)
- High-margin products: Low competition, goal is to protect margin (e.g., MATCH or ROUND strategy)
- Clearance products: Must be sold by year-end (aggressive min prices, selloff mode)
This way, on event day you just flip a switch instead of frantically changing parameters.

4. Repricing DURING Q4: Three Modes for Three Situations
During Q4, your repricing does not run on autopilot. You need three clearly defined modes that you switch between depending on the situation.
Mode 1: Aggressive (Event Days)
On Prime Big Deal Days, Black Friday, and Cyber Monday, it is about volume. Demand is so high that even small price advantages have massive impact on sales velocity.
In practice: set your repricing strategy to its most aggressive variant. If you normally run ROUND or MATCH, switch to JUMP or STEP on event days. Reduce the backoff value so your repricer drops faster. And increase repricing frequency if your tool allows it.
With arbytrage.io, you can set individual strategies for each product and switch instantly -- without touching each listing one by one.
Mode 2: Backoff (High-Margin Products)
Not every product needs a price cut on Black Friday. If you are the only FBA seller on a listing or your product is in high demand, lowering the price is counterproductive.
In this case: activate backoff mode. Your repricer stays at the upper end of your price range and only lowers the price when a competitor actually enters the BuyBox. This preserves your margin as long as demand outpaces competition.
Mode 3: Seasonal Price Increase (Scarce Inventory)
This sounds counterintuitive, but in Q4 you can raise your max price for certain products. If your inventory is limited and demand is rising, you do not want to sell at the same price as August.
Increase the max price by 10-20 percent for products you cannot reorder. Your repricer will automatically raise the price when competition thins out -- and that is exactly what happens in Q4 when other sellers run out of stock.

5. Black Friday and Cyber Monday: Repricing in Detail
Black Friday and Cyber Monday are the two most important days on the Amazon calendar. Here is your repricing strategy, day by day.
Monday to Wednesday (Black Friday Week)
Amazon starts deals week early. From Monday, traffic rises noticeably. Your repricing should already be set to "aggressive," but not at maximum. Lower your min price by 5-10 percent compared to your normal value -- but do not go to your absolute minimum. The real buyers come on Friday.
Thursday (Thanksgiving)
In the US, Thursday is Thanksgiving -- and Amazon is already running at full speed. For EU sellers, this is the eve of the main event. Check your inventory one last time and make sure all strategies are active.
Friday (Black Friday)
The big day. And here is the most important tip: Do not automatically drop to your min price. Demand on Black Friday is so high that many buyers will purchase at higher prices. Going too low too early means giving away margin.
Recommendation: start the day with your normal aggressive repricing. Check your sales velocity around noon. If you are significantly above plan, raise the min price slightly. If you are below plan, lower it.
Saturday and Sunday
Most sellers neglect the weekend after Black Friday. That is a mistake -- demand stays high. Keep your aggressive repricing running.
Monday (Cyber Monday)
For electronics, software, and digital products, often stronger than Black Friday. For all other categories, still a top day. Same strategy as Friday: aggressive, but not blindly at minimum.
The Golden Rule
High demand does not automatically mean you need the lowest price. The BuyBox rotates faster on event days anyway. As long as you are in the competitive range, you will get sales. Better to have 50 sales at 3 EUR margin than 60 sales at 0.50 EUR margin.

6. Christmas Repricing: The Final Two Weeks
After the Black Friday rush comes the phase many sellers underestimate: the last two weeks before Christmas.
Watch the FBA Cutoff
Around December 15-17, Amazon closes the window for new FBA shipments that will be available before Christmas. From this point, you work exclusively with inventory already in FBA warehouses.
This has direct implications for your repricing: if your inventory is running low, raise the max price. If competitors are out of stock, raise the min price. You are in a position of power -- use it.
Final Price Adjustments (December 18-23)
The last days before Christmas are pure gold. Last-minute buyers are the least price-sensitive customer group of the entire year. They need a gift, and they need it now.
For this phase: raise your min price by 10-15 percent. Your repricer will no longer drop to rock-bottom prices, and that is the right call. Competition is thinner, demand remains high, and every sale delivers above-average margin.
December 24-25
Christmas Eve and Christmas Day: barely any sales, no action needed. Use the quiet time to evaluate your Q4 numbers and prepare your selloff strategy for January.

7. After Q4: The January Selloff Strategy
Q4 is over, but your repricing work is not done. January is the month when poor Q4 planning gets punished -- through long-term storage fees.
Avoid Long-Term Storage Fees
Amazon charges long-term storage fees for inventory that has been in FBA warehouses for more than 181 days. If you ordered big in September and did not sell everything, the clock is ticking.
On December 26, review your inventory and identify products that will hit the 181-day threshold in January or February. These products get aggressive pricing immediately.
Lower Prices for Remaining Stock
For excess Q4 inventory, the rule is simple: better to sell at a small margin than to pay long-term storage fees. Lower the min price to purchase cost + Amazon fees + 1 EUR. Set the repricing strategy to JUMP or STEP so your repricer undercuts as aggressively as possible.
For products that will not sell even with aggressive repricing: check whether a removal order is cheaper than the cumulative storage fees.
Plan for Returns
In January, returns spike massively -- typically 15-25 percent of holiday sales. Your inventory grows again. Factor this into your selloff planning and do not reset the min price to normal levels too early.

9. Frequently Asked Questions
Should I drop to my absolute min price on Black Friday?
No. This is one of the most common mistakes. Demand on Black Friday is so high that you can win the BuyBox even with a price that is 5-10 percent above your minimum. Start moderate and only lower if your sales velocity falls significantly behind expectations.
How early should I switch my repricing to Q4 mode?
By mid-September at the latest. Preparation (inventory analysis, min price calculation, strategy profiles) takes two to three weeks. And Prime Big Deal Days in October come faster than you think.
Does aggressive repricing make sense for private-label products?
Yes, but differently. With private-label products, you have no direct BuyBox competitors. However, conversion rates still increase when your price drops slightly on event days. Use your repricing to run time-limited discounts and raise the price again immediately after.
What do I do if my inventory runs out mid-Q4?
Raise your min price immediately and reduce your repricer's aggressiveness. Better to sell 10 units at 8 EUR margin than 20 units at 2 EUR margin and then be out of stock. If restocking is possible, use FBM as a bridge until FBA inventory is replenished.
How do I avoid long-term storage fees after Q4?
Starting December 26, check all products that will reach the 181-day threshold within the next 60 days. For these products, set the min price to break-even and activate the most aggressive repricing strategy. If that is not enough, a removal order is the better option compared to months of storage fees.

Conclusion
Q4 is not a sprint -- it is a 4-month marathon from September to January. Your repricing needs to move with it: conservative preparation in September, aggressive execution on event days, smart margin protection in December, and disciplined selloff in January.
Sellers who approach Q4 systematically do not just generate more revenue -- they generate revenue with better margins. Because they know when to be aggressive and when to ease off the gas.
Your repricer is your most important tool in Q4. Make sure it is configured correctly.
