FBA Refund RadarAmazon's FBA policy promises reimbursement for lost and damaged inventory - but only if you file before the claim window closes. FBA Refund Radar cross-checks your Seller Central reports, finds every unclaimed or underpaid reimbursement, tracks each 18-month filing deadline, and drafts the appeal letters - for a flat $29/mo instead of the 25% cut refund agencies take.
