Authorized retailer data
A store is published only after program approval and documented permission for its product catalog or API.
PriceFlock is building a multi-retailer catalog from official APIs and approved affiliate feeds. Every public offer must be current, attributable, and matched to the exact product variant.
Every product below has at least one authorized offer checked within the last 5 hours.

Each guide explains what must match before prices can be compared.
A store is published only after program approval and documented permission for its product catalog or API.
The catalog is designed for 6 refresh cycles per day. Offers older than 5 hours are hidden.
UPC, GTIN, model, size, color, condition, and pack details must agree before offers share a comparison page.
PriceFlock does not process checkout, rewrite retailer terms, or publish a catalog before authorization. Retail partners keep control of destination URLs and can request corrections or removal.
PriceFlock is a US-first product discovery and price-comparison service. It does not sell products or process payments. Approved offers are grouped only when identifiers and material variant details agree, then shoppers complete every purchase on the retailer’s own website.
Product images and offer details must come from the authorized source that supplied the current listing. Scraped retailer pages, undated legacy records, fabricated discounts, and unverified store relationships are excluded from public results.
