You find the good listings after they sell

  1. 1You refresh saved searches all day, and the best listings are gone in minutes.
  2. 2A lead list goes to every member of its group, so other sellers see the same deal.
  3. 3Even when you spot one, you do the Amazon fee math in another tab, and it is slow and easy to get wrong.

Your catalog in, only the deals that clear your profit line out

Matched to your products
You upload the products you already sell, from your own Seller Central report. Every new eBay listing is checked against them by model number and UPC, and we read kit versus bare tool and lot size from the title. Each alert shows a match confidence score.
Profit worked out for you
Each alert shows the eBay price, your Amazon price, the Amazon fees, and your estimated profit and ROI. Prices and fees come from the reports you upload, dated in every alert, or live if you choose to connect your seller account. A lot of 3 is priced as 3.
Only what clears your line
You set a minimum profit and ROI. A green or amber flag tells you where each deal sits, and anything under your line never reaches your phone.

How it will work

  1. 1

    Give us your products.

    Upload the All Listings Report from your Seller Central, or connect your Amazon seller account (read-only) for live prices. No connection is required.

  2. 2

    Set your profit line.

    Choose the minimum profit and ROI you care about. Listings under your line never reach your phone.

  3. 3

    Get the alert on your phone.

    Alerts arrive on your phone through Telegram, with the eBay listing and the Amazon math in separate blocks.

Each alert also shows the listing's timestamp and ours, so you can judge how fresh it is. The buy link opens eBay, and you buy it yourself.

What an alert looks like

The eBay listing and our Amazon math arrive as two separate blocks, so you always know which numbers come from where.
