Chrome extension for eBay resellers

Add to Chrome — Free See pricing

Free tier included. No ads or redirects. Your eBay research data stays on your device.

Listed on the Chrome Web Store as eBay Sold History & Profit Calculator.

What it does

Four focused tools, built for people who actually sell on eBay.

🔍

Sort by Sold

Sort any eBay search by sold count and popularity in one click, so you see what actually moves — not just what's listed.

  • One-click sort on any eBay search results page
  • Surfaces the fastest-selling listings first
  • Works instantly — no reset, no ads, no redirects
💰

Sold Comps Panel

Click any item or search and get an instant read on real market pricing, pulled straight from eBay's own public sold and completed listings.

  • Median sold price, price range, and items sold in the last 30 days
  • Read-only — pulls from eBay's own public data
  • Appears on any product page or search result
📊

Net Profit Calculator

Enter your item cost and shipping cost. The calculator applies the published fee rules for your selected category or seller type to show your real take-home — not just the gross sale price.

  • Accounts for final value fees, per-order fees, promoted listings, and international fees
  • Shows a full breakdown of every deduction, not just a total
  • Free and unlimited on every plan
  • Pro adds ROI, break-even buy price, and a maximum buy price for your target margin
📋

Search Report

On any eBay search, open a sortable report of every listing on the page — title, price, sold count, watchers, and bids — built entirely from the page you're already viewing.

  • Sort by price, sold, watchers, or bids; download as CSV
  • Built from on-page data only — no extra requests to eBay
  • Available on the Pro plan

Changelog

What changed, what is live, and what is still waiting for store review.

v0.1.2

Next store update
  • Larger calculator popup: inputs and results now sit side by side, so the extension popup no longer needs routine vertical scrolling; the sourcing Unlock link opens the product site.
  • Same calculator on the item page: the calculator inside the sold comps panel now uses that same side-by-side layout, so a product page shows comps and net profit together without scrolling.
  • Pro sourcing targets: see ROI on item cost, break-even buy price, and the maximum buy price that still reaches your chosen profit margin.
  • Better follow-up: an optional rating or feedback prompt appears no sooner than seven days after installation; rating is never required for the feedback reward.
  • UK fix: calculator results and sourcing targets now use pounds instead of dollar symbols on ebay.co.uk.
  • Store readiness: clearer privacy disclosures, refreshed listing copy, and updated Chrome/Edge submission guidance.

Prepared for submission. These changes are not in the current Chrome Web Store build until v0.1.2 is approved.

v0.1.1

Current store version
  • Added the Pro sortable search report with CSV download.
  • Made the complete net profit calculator free and unlimited.
  • Added on-page demand ratio and sample median sold-price statistics.
  • Improved same-origin sold-data fetching and current eBay layout compatibility.

Privacy & trust

No ads, redirects, or analytics. Page data is used only for the visible tools and is not sent to us.

🚫

No ads, no redirects

The extension never injects ads, affiliate links, or redirects into any page you visit.

🔒

Runs locally

Sorting, comps parsing, and profit calculations all run in your own browser. There is no backend server of ours that the extension reports to.

👁

No analytics or telemetry

We don't run any analytics, crash-reporting, or telemetry SDK, and we don't log your searches or pricing data.

One honest exception, disclosed up front: if you upgrade to Pro, checkout is handled by Paddle, our payment provider and Merchant of Record, which processes your card payment and applicable tax on a page outside the extension. The extension itself contacts only our own license-validation service to check whether your subscription is active — never Paddle directly, and never with your eBay searches, browsing activity, or any comps/pricing data included. Full detail, including exactly what's stored and why, is in our Privacy Policy.

Frequently asked questions

How does it interact with eBay?

It reads public listing pages — no account access or automation. It doesn't modify listings, automate bids, or change any account settings.

Why use this instead of switching between pages and a spreadsheet?

It keeps sold-count sorting, comparable prices, a search report, and an editable profit calculator together while you browse eBay on desktop.

Will this break when eBay redesigns its pages?

eBay page changes can affect any browser extension. We monitor feedback, test parser changes, and publish compatibility updates when needed.

Do you store my searches or pricing data?

The extension temporarily stores a one-hour comps cache and the latest generated search report in your browser so the tools work without repeating requests. That page-derived data is not sent to us, and we don't operate a server that logs your searches, prices, or browsing activity. See the Privacy Policy for the full technical detail.

Found a bug? Have an idea?

We're in public beta, and we read every email. Actionable product feedback or a confirmed issue earns a free month of Pro. A store rating or review is never required.
