Sourcerer Arbitrage: research Amazon resale opportunities, automatically

Sourcerer Arbitrage scans supported retail sites, finds candidate Amazon matches, and estimates ROI and sales velocity to help you research a buylist. Verify matches, current costs and resale eligibility before buying; estimates do not guarantee profit.

What it does

Automated scanning. Crawl retail sites by brand or keyword, or walk their clearance aisles, then look up candidate Amazon matches by UPC, EAN, or title.
Smart gating. Check whether Amazon will even let you list an ASIN (Eligible, Gated, or Blocked), then filter what is left by your own ROI, BSR and offer-count rules.
Price-drop tracking. Re-scan a site and every price is checked against that product's own history, so the biggest markdowns since you last looked rise to the top.
Actionable analytics. Track ROI distribution, BSR spread, velocity verdicts, and your top performers on charts built from your own scans.

Supported retailers

Search any of these 24 by brand or keyword: Kohl's, Target, Walmart, Finish Line, Vitacost, The Home Depot, Macy's, 888 Lots, Blair Candy, Christianbook, PetSmart, Lulu, Academy Sports, iHerb, Jenson USA, YesStyle, LightInTheBox, Entertainment Earth, Chewy, CVS, Best Buy, Nordstrom, Nike and Dick's Sporting Goods.

Clearance-aisle and whole-catalog walks cover the retailers that publish a sale listing or a browsable one.

How it works

Connect and scan. Authorize your Professional Seller account through Connect with Amazon in Settings, then point Sourcerer Arbitrage at a brand or a site and watch the scan run live.
Review candidate leads. Filter estimated ROI, velocity and price drops by your own rules, then run an eligibility check on the shortlist you keep.
Verify before you buy. Check each match, its current cost and your resale eligibility, then track what you are watching or have already bought.

Sign up in a minute: pick a plan, and your account opens as soon as payment succeeds. Cancel any time. Available to US residents and to EU businesses with a VAT number. Every request our scraping provider makes for you counts as one page, including each page of search or listing results and each repeat, even one that finds nothing. Clearance-aisle, catalog and Kohl's walks also count each product they read, once per product per day. A walk that returns 250 products can therefore spend more than 250, and scanning every supported retailer in one click can spend a few thousand. Before you start a capped run, the scan form says how many listing pages it can walk and what else it counts.

Amazon matching, ROI grading and eligibility checks run on your own seller authorization, so you will need a Professional Seller account connected through Connect with Amazon in Settings. You approve the access on an authorization page that Amazon hosts, and Settings never asks for a key. Retail scanning works without connecting.
