Every fact on this page is sourced directly from each provider's own published material — official websites, help centers, and pricing pages — with a source link and a verification date kept for every fact group, not just the page as a whole.
When a fact genuinely isn't published anywhere we checked, it is labeled "not yet confirmed" rather than guessed at or silently treated as a "no". A confirmed absence (like "no stated order minimum") is only ever shown when a provider states that directly — it is never the default.
This directory does not use star ratings, scores, or a "best" ranking. Providers are labeled "CartEconomics Researched" once their core facts have been checked against official sources — that label describes research effort, not a certification or endorsement from the provider itself.
