Prime Big Deal Days Returns October 7–8: How Sellers Can Prepare for the Fall Sales Event
Prime Big Deal Days is set for October 7‑8 2025. Sellers must have FBA stock in place by mid‑September (≈Sept 15) and can raise Sponsored Product daily budgets by 75% from October 1. All deal types—Lightning, Best, coupons, vouchers—are accepted.
Overview
Amazon has locked in October 7–8, 2025 for Prime Big Deal Days, a two‑day sales sprint reserved for Prime members. The event serves as an early Q4 catalyst, giving third‑party sellers a chance to clear inventory, capture new shoppers, and generate momentum before the Black Friday‑Cyber Monday rush. Preparing now can mean the difference between thriving sales and missed opportunities.
Key Points
- Confirmed dates — The event will run on October 7 and 8, 2025, giving sellers a fixed planning window.
- Promotion flexibility — Deals, vouchers, and advertising can be launched any time before or during the two days.
- Full ad suite access — Sponsored Products, Sponsored Brands, and Sponsored Display are all eligible for the traffic surge.
- All deal formats accepted — Lightning Deals, Best Deals, coupons, and vouchers can be submitted for the event.
- Inventory deadline — FBA shipments should arrive 2‑3 weeks early, meaning sellers must ship by mid‑September at the latest.
- Ad budget guidance — Experienced sellers often raise spend by 50‑100 % during major sales windows to stay visible.
How Prime Big Deal Days Works
- Deal creation and submission — Sellers submit Lightning Deal or Best Deal requests through Seller Central weeks ahead of the event; Amazon reviews and assigns slots based on performance history and inventory.
- Inventory placement — Accepted deals require stock to be stocked in Amazon fulfillment centers at least 14 days before October 7, ensuring the product can be shipped immediately once the deal goes live.
- Advertising activation — Sponsored campaigns can be launched or amplified up to the start of the event; bids are automatically adjusted by Amazon’s algorithm to compete for the heightened shopper volume.
- Deal activation — On October 7 at the scheduled time, qualifying listings display the deal badge, and the discount is applied at checkout for Prime members.
Analysis & Recommendations

If inventory isn’t in Amazon’s fulfillment network by the Sep 15 deadline, deal slots can be rejected, losing exposure during the two‑day traffic surge. Raising ad spend by up to 75% helps maintain visibility as competition spikes, driving higher conversion and Q4 revenue.
