Limitation of liability: CrateFit is provided as-is. We do not guarantee fitness for a particular purpose, correctness of third-party fee schedules, or that Amazon will apply the same fee we estimated. You are responsible for reconciling against your Amazon Seller Central invoice.

Changes: we may update these terms. The Last updated date will reflect the most recent change. Continued use after a change is acceptance of the new terms.
