You're reading this during the biggest October shopping event in ecommerce history. Prime Big Deal Days started yesterday at 12:01 a.m. PDT. Day 2 is today. New deals are dropping three times daily — midnight, 8 a.m., and 1 p.m. Forty-eight hours across 35+ categories and 22 countries.

But Amazon isn't alone. Walmart Deal Days is running October 5-11. Best Buy launched its Techtober event. Target is matching prices across categories. For the first time, October has become a genuine multi-retailer battleground — not just an Amazon event.

Meanwhile, FBA Q4 rates have been live for a week. The peak surcharge hits in 8 days. BFCM deal submissions close in 13. And this week's data tells you exactly what will and won't work on Black Friday.

Five things to execute today, this week, and over the next 51 days.

The event is happening right now. If you're a seller, stop skimming and start monitoring. Prime Big Deal Days runs through 11:59 p.m. PDT tonight. Every hour matters.

What to do RIGHT NOW:

✅ Check your campaigns hourly. Traffic spikes 3-4x during Prime events. If your Sponsored Products or Sponsored Brands campaigns went out of budget overnight, you missed the midnight deal drop and the early morning wave. Increase budgets immediately.

✅ New deal drops at 1 p.m. PDT today. The afternoon wave is the third and final daily drop. Shoppers who missed morning deals come back. This is your best window for incremental conversions if you're running coupons or promotions.

✅ Monitor Best Seller Rank (BSR) in real-time. Prime Big Deal Days creates ranking momentum that carries into the weeks after the event. Products that climb BSR during the event hold better organic positioning through Black Friday.

✅ Price history is 365 days. Amazon expanded visibility to a full year. Every shopper can see if you raised prices before the event to inflate discounts. Clean pricing is the only pricing that works now.

✅ Build retargeting audiences TODAY. Every shopper who clicks your listing during Prime Big Deal Days but doesn't buy is a future Black Friday conversion. Set up your Sponsored Display retargeting audiences before the event ends tonight.

💡 The deal drop schedule: New deals at midnight, 8 a.m., and 1 p.m. PDT. Time your budget allocation to these windows. A flat budget across 24 hours wastes spend during low-traffic hours and runs dry during the peaks.

For the first time, October has become a genuine multi-retailer battleground. Amazon started it with Prime Big Deal Days in 2022. Now everyone runs competing events during the same window. If you sell on multiple channels, your strategy this week needs to account for all of them.

Who's running what:

✅ Walmart Deal Days: October 5-11 — a full 7-day event surrounding Amazon's 48 hours. Walmart is playing the "we're open to everyone" card — no membership required. Discounts across electronics, home, fashion, and grocery. Walmart's ecommerce grew 23% last quarter. They're spending their tariff refund on lower prices.

✅ Best Buy Techtober — targeted at electronics and tech shoppers. My Best Buy members get early access and exclusive pricing. If you sell electronics or tech accessories, this is the competing event pulling your traffic.

✅ Target Circle deals — Target is matching and undercutting across key categories. Circle members get 20% off one purchase during the window.

✅ Dick's Sporting Goods — up to 50% off select products in their "3 Days of Savings" event.

💬 Stat: During Prime Day in June, total US ecommerce sales across ALL retailers hit $26.4 billion (DC360). The October event won't match that, but the competitive halo effect means every channel benefits from the traffic surge. Shoppers don't comparison-shop on one site — they bounce between Amazon, Walmart, and Target in the same session.

💡 Multi-channel action: If you sell on Amazon AND Walmart/your own site, run coordinated promotions. Don't let your DTC site sit dark while your Amazon listing runs deals. Capture the comparison shoppers wherever they land.

Two critical deadlines are racing toward you while Prime Big Deal Days absorbs your attention. Don't let the event distract you from the dates that determine your Black Friday performance.

October 15: Peak fulfillment surcharge goes live (8 days)

✅ Starting October 15 through January 14, 2027, every FBA order ships with an additional ~$0.32 per unit surcharge. This stacks on top of the Q4 storage rate ($2.40/cu ft) and the ongoing 3.5% fuel/logistics surcharge.

✅ If you haven't re-run your contribution margin with the full fee stack ($2.40 + $0.32/unit + 3.5%), do it this week. The combined impact on a $25 standard-size product is roughly $1.35/unit in additional fees versus September.

✅ On 10,000 units through Q4: that's $13,500 in additional fees you didn't have last month.

October 20: BFCM deal submission deadline (13 days)

✅ Lightning Deals and Best Deals for Black Friday Week and Cyber Monday close for submission on October 20. If you haven't submitted, do it this week. Not next week. This week.

✅ Last year, sellers who submitted after October 15 saw significantly higher rejection rates. Early submissions get reviewed first and approved first.

✅ Your BFCM deals should reflect what you learned from Prime Big Deal Days. Which products moved? Which price points converted? Which creative drove clicks? Use this week's data to optimize your submissions.

💡 The rhythm: October 7 (today) = learn from Prime Big Deal Days. October 8-14 = optimize BFCM submissions. October 15 = peak surcharge goes live. October 20 = submissions close. Execute this sequence.

Prime Big Deal Days isn't just a revenue event. It's a data event. The shopping patterns, conversion rates, and competitive dynamics you see this week are a preview of Black Friday. The sellers who treat it as a dress rehearsal win November. The sellers who just count sales miss the intelligence.

Measure these 5 things before the event ends tonight:

✅ Conversion rate by traffic source. Did Sponsored Products convert higher than Sponsored Brands? Did Sponsored Display retargeting outperform prospecting? The channel mix that works during Prime Big Deal Days will work on Black Friday — at higher volume and higher CPCs.

✅ Price elasticity by SKU. Which products moved at 15% off? Which needed 25%? Which didn't move at any discount? This tells you exactly how to price your Black Friday deals.

✅ Ad creative performance. Which headline, image, or video drove the highest click-through rate? You have 51 days to iterate on the winners before Black Friday.

✅ Competitor pricing and positioning. What were your top 3 competitors' prices during the event? Are they running the same discount structure you planned for Black Friday? If yes, you need a different angle.

✅ BSR movement and ranking momentum. Products that ranked up during Prime Big Deal Days carry momentum. Products that ranked down lost ground. Adjust your Black Friday inventory allocation based on what moved.

💬 Stat: Salesforce found that merchants running AI-powered tools grew holiday sales 59% faster (6.2% vs 3.9%). The intelligence advantage from Prime Big Deal Days compounds if you use it. Don't just check revenue. Check what the data is telling you about November.
