Prime Big Deal Days is Amazon’s major fall shopping event, running Oct. 7–8, 2025, and offering exclusive discounts for Prime members. While the company’s main Prime Day event usually takes place in July, the fall sale is often nicknamed the “October Prime Days,” giving shoppers a second chance to grab big savings ahead of the holiday season.
In this primer, we’ll cover everything you need to know about Prime Big Deal Days, including how to sign up for a free Prime trial, get early access to hot products, and secure the best deals.
What Are Prime Big Deal Days?
Along with Prime Day, Black Friday, and Cyber Monday, Prime Big Deal Days are one of the best annual opportunities to score Amazon deals. The event began in 2022 as the “Prime Early Access Sale” and was renamed “Prime Big Deal Days” in 2023. Amazon created this sales event to give Prime members a second major sales event in the fall, complementing the traditional Prime Day in mid-July.

Prime Big Deal Days 2025 are scheduled for Tuesday, Oct. 7, starting at 12:01 a.m. PT and 3:01 a.m. ET, and will run through Wednesday, Oct. 8, ending at 11:59 p.m. PT and 2:59 a.m. ET on Thursday, Oct. 9.

Learn To Spot the Best Deals
Prime Big Deal Days offers discounts across a wide range of products, but not every deal is truly a bargain. Early deals began right after Amazon’s Sept. 29 announcement, with discounts going live on Oct. 1. Amazon is rolling out new offers daily, giving Prime members an early chance to grab gifts and essentials before the Oct. 7–8 event. Check the “Early Prime Days” section on Amazon’s main page, where deals are running up to 40% off.
Here are some tips to make sure you’re getting the best value:
- Watch for the “lowest price in 30 days” tag, which often signals a deeper-than-usual discount.
- Check different colors, sizes, or models—less popular variations often come at a lower price.
- Last year’s models, especially in electronics, are frequently discounted more heavily.
- Compare prices with other major retailers, since many run competing sales during Prime Big Deal Days.
- Watch for Lightning Deals, also listed under “Today’s Deals.” These are limited-quantity offers that can sell out quickly but often provide some of the steepest discounts.
