Q4 2026 peak storage and PPC pacing
Direct answer: Q4 2026 has two fee windows that do not line up. Peak storage is October–December. Peak fulfillment is 15 Oct 2026 – 14 Jan 2027 (Amazon Holiday 2026 Seller Forums). Recalculate break-even ACOS when either window opens. Do not protect rank on SKUs that drop under your margin floor.
The two clocks
| Window | When (2026–27) | What it does to ads |
|---|---|---|
| Peak storage | 1 Oct – 31 Dec | Holding slow units gets expensive. Excess inventory is a bid input — you cannot rank what you should have removed. |
| Peak fulfillment | 15 Oct – 14 Jan | Per-unit fulfillment rises (Amazon cited ~$0.32 average over non-peak, plus fuel surcharge). Contribution falls. Target ACOS must fall with it. |

What to do this week (late September)
- Pull FBA Fee Preview on hero ASINs. Add a peak-fulfillment buffer and rerun the break-even ACOS calculator.
- Cut bids on SKUs that drop under your contribution floor. Peak volume will not rescue an underwater ASIN.
- Do not raise discovery budgets “for Q4.” Exact on converters; discovery on a leash.
- If inbound will miss the Black Friday eligibility dates, pause ranking campaigns on those ASINs now.
FAQ
Is 1 October or 15 October the deadline?
Storage steps up 1 Oct. Fulfillment surcharge starts 15 Oct. Drawdown decisions are governed by the October storage snapshot — earlier, not later.
Should I raise budgets for Black Friday now?
Only on exact converters that still clear the new fee stack, with daily budgets that last through evening hours. Discovery stays on a leash.
