Original evidence behind MainBuyer buying intelligence

These datasets contain facts recorded or calculated by MainBuyer rather than copied from editorial prose: dated retailer-price observations, verified recurring ownership costs and manufacturer-backed model relationships.

What is published here

Price datasets retain the timestamp and retailer context of real checks; missing dates are not reconstructed. Ownership datasets retain verified recurring costs and only publish a complete 1, 3 or 5 year ownership total when research coverage is explicitly confirmed and a checked acquisition price exists.

Model-lineage datasets retain manufacturer-backed predecessor, successor, same-family and regional-variant relationships. Automated research cannot create cross-brand lineage.

Every dataset links back to the normal product review, and machine-readable JSON is available from the individual evidence pages.
