Tactical Arbitrage Extension: Which One Do You Actually Need?

There is no official Chrome extension called Tactical Arbitrage. I searched the Chrome Web Store while writing this page, and the only results under that name are two third-party tools.

The extension most sellers actually want is ScoutX. It ships inside the same Seller 365 subscription as Tactical Arbitrage, from $69 a month. If you already pay for the platform, you own it.

Key Takeaways

• No standalone official extension: a Chrome Web Store search for the name returns third-party TacticalBucket tools.
• ScoutX is the real answer: profit, fees, and rank data on Amazon and Walmart pages, included with every Seller 365 plan.
• Two smaller official add-ons: Restrictions Detective checks gating and Hazmat; Hummingbird Hover-Graph charts price history free.
• One is gone: the old Popular Products extension no longer exists in the store.
• The third-party route costs extra: TacticalExpander needs a TacticalBucket plan at $39 to $99 a month.

Why There Is No Official "Tactical Arbitrage Extension"

Tactical Arbitrage runs as a cloud web app, not a browser add-on. Its scans cover 1,386 retail sites and 12 Amazon marketplaces from Threecolts' servers. A search keeps running after you close the laptop. Extensions in this ecosystem handle the smaller jobs: on-page checks, price charts, and site expansion.

The confusion is old. A widely shared 2020 roundup even described Tactical Arbitrage itself as "a paid Chrome extension," and that framing stuck in Facebook groups.

The official sites counter read 1,386 sourcing sites when I checked, with custom-site adding gated behind the Advanced User feature.

So what do people mean by "the Tactical Arbitrage extension"? Five different tools.

The Tactical Arbitrage Extension Map: All 5, Verified

Five tools answer this search. Three are official Threecolts listings, one is officially dead, and the loudest result in Google is third-party. The user counts and ratings below come straight from each Chrome Web Store listing, checked one by one.

The pattern behind the numbers: official add-ons stay small because the web app does the heavy lifting, and the biggest install base belongs to the one extension that checks what you are allowed to sell.

ScoutX: The Extension You Actually Get With Tactical Arbitrage

ScoutX is the browser extension Threecolts bundles with Tactical Arbitrage in every Seller 365 plan. Version 2.1.3 landed in November 2025. The widget reads profit, fees, sales rank history, variations, and Buy Box activity on Amazon and Walmart product pages. About 4,000 sellers run it at a 4.3-star rating.

Threecolts' own store screenshot shows the full readout on a $31.71 listing: net profit split for FBA and merchant-fulfilled, margin percentages, and rank drops counted across 30, 90, and 180 days.

The division of labor is deliberate. Tactical Arbitrage runs the bulk scans overnight; ScoutX validates single products while you browse. The widget even carries quick links that push a product into a deeper Tactical Arbitrage analysis, and Walmart research runs through the same panel.

Operator scenario: Say a lead group drops one Target clearance find in your chat. Instead of opening the web app, you click the ScoutX icon on the Amazon match, read fees and the 90-day rank in the widget, and only send it to a full Reverse Search if the margin clears 30%.

Grab it from the ScoutX listing and log in with your Seller 365 account.

The Two Smaller Official Add-Ons

Threecolts keeps two niche extensions alive under the Tactical Arbitrage name. Restrictions Detective serves 7,000 users at a 5.0-star rating. Hummingbird Hover-Graph serves 1,000 at 4.6 stars. Neither replaces ScoutX; each one solves a single, specific sourcing problem and takes under a minute to install.

Restrictions Detective: Gating and Hazmat Checks

Restrictions Detective adds a "Check Restrictions" button to Tactical Arbitrage View Data pages. It reads your Amazon Seller Central login and flags product, category, and brand restrictions plus Hazmat status for your account. The extension weighs 17KiB, holds a 5.0-star rating, and requires an active Tactical Arbitrage subscription.

Operator scenario: Say a scan surfaces 40 Bath and Body Works products. One click per row shows which ones your account can list today, which need approval, and which fail Hazmat. Ten minutes of clicking beats a pallet of inventory you cannot sell.

Expand

The listing carries a verified tacticalarbitrage.com publisher badge, 7,000 users, and a 5.0 rating from 4 reviews. The demo shows approval and Hazmat flags on Bath and Body Works results.

Install it from the Restrictions Detective listing, then look for the green button on any View Data page.

Hummingbird Hover-Graph: Free Price-History Charts

Hummingbird Hover-Graph is the free one. Click the extension icon on any Amazon product page and a chart of price and sales rank history pops up. Everyone gets 5 free pulls a day. Tactical Arbitrage subscribers get unlimited pulls plus a direct Tactical Edge link for deeper analysis.

Operator scenario: Say a thrift-run recap leaves you 12 ASINs to sanity-check at night. The first 5 charts cost nothing. Past that, either wait for the daily reset or log in with your subscription and clear the whole list in one sitting.

Expand

The official demo overlays the hover graph on an Amazon listing: price on the left axis, rank on the right, with range toggles from 2 days to a full year.

Five daily checks run out fast in a real sourcing session. Sellers who live inside price-history charts usually run the Keepa extension alongside it, and our review covers when the paid Keepa data plan earns its fee. The free Hummingbird Hover-Graph listing is still worth pinning for quick spot checks.

TacticalExpander: The Third-Party Extension Ranking First

TacticalExpander is the third-party extension that outranks everything else for this search. TacticalBucket.com builds it, not Threecolts. It feeds Tactical Arbitrage more than 400 extra retail sites through custom XPaths. The Chrome listing shows 3,000 users and a 3.0-star rating from 4 reviews.

TacticalBucket is a whole add-on ecosystem: daily bulk lists, private XPaths, wholesale-site scans, and an ASIN extractor, all synced into Tactical Arbitrage with one click. Plans run from a limited free tier to $39, $49, and $99 a month.

TacticalBucket's own screenshot inside Tactical Arbitrage: the Scan stores imported from TacticalExpander toggle, with an Easy Scan panel feeding nike.com into the search.

The 4 store reviews split hard. One praises the developer by name for same-day fixes. Another calls the imported data inaccurate and reports a subscription that took months to cancel. The store also labels the developer a non-trader, which waives EU consumer protections. Real upside, real friction: weigh both before paying. You can inspect the TacticalExpander listing yourself before committing to a plan.

What Each Option Costs

Every official extension rides on the Seller 365 subscription. Plans start at $69 a month and include a 14-day free trial. TacticalExpander bills separately through TacticalBucket. Hummingbird stays free at 5 checks a day. Here is the math side by side.

Expand

Threecolts' Seller 365 pricing cards: Standard $69, Teams $129, and Pro $199 a month, each with a 14-day free trial and full access to the 10-tool bundle.

Plenty of blogs still quote retired plan numbers, so double-check anything you read against checkout. The Tactical Arbitrage pricing page breaks down how the old standalone tiers compare with the bundle, and the Tactical Arbitrage free-trial walkthrough covers the signup flow.

Which Extension Should You Install?

Match the tool to the job. Five jobs cover most sourcing sessions, and four are already paid for inside the $69 Seller 365 subscription. Only one option asks for extra money, and only once you outgrow the 1,386 sites the platform already scans.

• Vetting one product while you browse: install ScoutX. It is already in your bundle.
• Gating and Hazmat checks before buying: add Restrictions Detective to your View Data workflow.
• Quick price-history charts: Hummingbird covers 5 a day free; chart-heavy sellers pair it with Keepa.
• Sourcing from sites Tactical Arbitrage lacks: TacticalExpander via TacticalBucket from $39 a month, eyes open on the 3.0 rating.
• Bulk scanning hundreds of sites: skip extensions entirely. The web app does this server-side.

Not a Seller 365 customer and not planning to be? Some sellers only want on-page analysis without a bundle. For that job, SellerAmp SAS starts at $19.95 a month and reads profit, eligibility, and Keepa charts on nearly any retail page.

Verdict: Install Two, Skip the Rest for Now

Install ScoutX and Restrictions Detective on day one. Both cost nothing beyond the Seller 365 plan and cover on-page validation plus gating checks. Pin Hummingbird as the free bonus. TacticalExpander only makes sense after 1,386 native sites stop producing enough leads for you.

• Start with: ScoutX plus Restrictions Detective, both included with your subscription.
• Add later: a TacticalBucket plan from $39 a month, once you need sites the platform lacks.
• Full context: my in-depth Tactical Arbitrage review rates the platform 4.3 stars and covers where the bundle beats standalone rivals.

Not inside Seller 365 yet? The 14-day trial is the cheap way to test the whole stack: run Tactical Arbitrage scans, click through the results with ScoutX, and let the numbers decide before the first invoice.
