The Six-Week Tactical Checklist for Amazon Prime Day 2026
A practical week-by-week guide to defending your brand on Amazon, eBay, and Walmart before, during, and after the largest 3P seller event of the year.
Amazon has confirmed Prime Day 2026 will return in June across 26 countries. 3P sellers now move 62% of every unit sold on the platform. The casual sellers left. The ones who stayed have a sharper playbook than they did last summer.
This checklist is what brand owners do about it. Six weeks. Six themes. Specific tactical actions that take 30 minutes to two hours each.

Six weeks. Six themes. One outcome.
Each week has an objective, a tactical to-do list, and one red-flag warning to watch for. The cadence assumes you start six weeks before Prime Day. Pick it up later and run two weeks at once.
WEEK 1
Audit and baseline
Know exactly what you’re defending. Pull your brand’s full ASIN inventory, count current 3P sellers, identify your priority defence targets and your high-risk back-door SKUs.
WEEK 2
Documentation and policy review
Confirm trademarks, audit reseller agreements, document your takedown templates. Brands that get same-day removals are the brands whose paperwork is in order.
WEEK 3
Detection and monitoring setup
See new sellers the moment they appear. Configure listing-level alerts across Amazon, eBay, and Walmart. Brief customer service and sales on what to flag.
WEEK 4
Engage and prepare
Test your enforcement process on real cases before Prime Day pressure makes mistakes expensive. File a test takedown. Document the response time end-to-end.
WEEK 5
Active enforcement sweep
Clear the listings before Prime Day traffic arrives. Sweep priority SKUs, file takedowns on every new unverified seller, tighten DTC store order limits.
WEEK 5
Prime Day live monitoring
Defend in real time. Daily checks, same-day enforcement filings, real-time price tracking, and a documented evidence file for the next enforcement cycle.
Built for brand owners. Read by everyone else.
Most Prime Day content online is written for resellers — how to find the deal, how to scan the catalogue, how to clear the gate. This is the opposite document.
Practical, not theoretical
Every action takes 30 minutes to two hours and requires no six-figure budget. Pull a spreadsheet. Send an email. File a takedown. Real work for real teams.
Cross-marketplace by default
Amazon, eBay, and Walmart. The 3P sellers preparing for Prime Day are listing across all three. Single-marketplace defence leaves the other two exposed.
Sourced from real brand defence
The tactics in this checklist come from real GreyScout customer engagements. The platform has delivered a 95% enforcement success rate across thousands of takedowns.
We monitor brands across Amazon, eBay, and Walmart so the people who own them don't have to.
GreyScout is a B2B brand protection platform built for the brand owner’s perspective on grey market activity. We track every new 3P seller, every Buy Box change, every pricing anomaly, and we flag it the moment it happens. This checklist is an extract of the tactics our customers run during Prime Day prep — distilled into a working document any brand team can use, with or without our platform.

Five questions before you download.
When is Amazon Prime Day 2026?
Amazon has confirmed Prime Day 2026 will return in June across 26 countries, with deals spanning more than 35 product categories. Prime members in Australia, Brazil, India, and Japan will shop later in the summer.
Prime Day amplifies the consequences of every gap. A 3P seller who ungated a brand in April is fully stocked, repriced, and ready to capture demand the moment Amazon turns the traffic taps on in June. The window to defend is the six weeks before, not the event itself.
Do I need GreyScout to use this checklist?
No. The checklist is structured to work whether you use GreyScout or not. Several actions are faster and more systematic with the platform — particularly the detection and enforcement-sweep weeks — but every action is doable manually with a spreadsheet, a Brand Registry login, and discipline.
How long does it take to work through?
Each week’s actions take a total of two to four hours of focused work. Across six weeks, that is the equivalent of one focused day of brand protection work — significantly less than the cost of one unverified seller capturing your Buy Box during Prime Day.
Six weeks is enough time to know who's listed against you.
