About Tomas Ferreira
Tomas Ferreira is the site's Research Editor, building comparison tables for most articles and maintaining its historical order database. His coverage includes agent fee tables, shipping-cost modelling, warehouse turnaround data, survey design and comparison tables. He manually rebuilds every agent fee table from a real checkout and compares final landed costs for the same basket across two or three shipping lines. He tracks warehouse turnaround through the agent dashboard and checks it against email timestamps. When the spread is wide, he publishes variance rather than only the average, and checks every number used in public content twice.
