Track Prices from Individual Sellers on Marketplaces

Why seller-level pricing matters

Product-level average prices hide the competitive dynamics between sellers. Understanding which sellers consistently undercut the market, which maintain premium positioning, and how pricing patterns differ across sellers provides richer intelligence for your pricing strategy.

Monitoring seller pricing with ShoppingScraper

ShoppingScraper's marketplace APIs return seller-level data including seller name, price, shipping cost, condition, and buy-box ownership. Track specific sellers over time to understand their pricing patterns and predict their behavior.

• Seller-level price and shipping data per listing
• Buy-box ownership tracking per seller
• Historical seller price trends

Actionable insights from seller data

Identify which sellers are your most aggressive competitors. Understand their repricing patterns, whether they react to your changes, and how quickly. Use this knowledge to craft pricing strategies that account for seller-specific competitive dynamics.

Real example: individual seller data from bol.com

A single API call to the bol.com offers endpoint for LEGO 10313 Icons Wildflower Bouquet (EAN: 5702017416663) returns individual seller-level data. Each seller has a unique offer with their own pricing, shipping policy, and condition — giving you granular visibility into who competes on your listings and at what price.

• bol (platform seller) — €45.75, free shipping, New — the buy box winner at the lowest price
• froqz retail — €54.90, free shipping, New — €9.15 above the lowest offer
• BrickTopia BV — €54.99, free shipping, New — competitive with froqz retail
• BRICKKampioen — €54.99, free shipping, New — matching BrickTopia's price exactly
• Each seller entry includes a unique offerUid reference for tracking over time
• Compare seller pricing strategies: bol undercuts by 17% while the other three cluster at the same price point

• Merchant modal: company info, address, country, TrustPilot scores, and 'Visit Store' button
• Merchant Lookup integration: one click from any seller to their full company profile
• Track seller pricing changes over time with the price history chart filtered per merchant
