A: Sum annual warehouse storage fees, insurance, obsolescence write-downs, and your working capital opportunity cost (typically 25% to 32% of trapped COGS per year). ### Q: Why is selling dead stock below unit COGS often more profitable than holding it? A: Unit COGS is a sunk cost. Recovering 75 cents on the dollar today stops monthly storage bleed and lets you reinvest that cash into high-velocity hero SKUs. ### Q: When does Amazon FBA charge the aged inventory surcharge? A: Amazon charges monthly aged inventory surcharges starting at 181 days in fulfillment centers, escalating sharply at 271 days and reaching $6.90+ per cubic foot at 365+ days. ### Q: How does a Free Gift With Purchase (GWP) recover more value than a steep discount? A: A SKU with $5 COGS and $28 retail price used as a free gift on orders over $80 increases average order value without cheapening your core brand pricing. ### Q: What do wholesale inventory liquidators typically pay for e-commerce closeouts? A: B2B closeout jobbers typically pay 10% to 30% of landed unit COGS (or 5% to 12% of retail price), making mystery bundles or VIP flash sales preferable whenever possible. ### Q: Are my SKU cost and inventory aging reports uploaded to any server? A: Never. All inventory aging calculations, markdown simulations, and CSV exports run 100% locally in your browser RAM with zero cloud uploads. ## Related Zero-Egress Local Appliances (XVibe Suite) - **Kubeconfig Secret Redactor**: https://xvibelabs.com/tools/068-kubeconfig-secret-redactor/ (`https://xvibelabs.com/tools/068-kubeconfig-secret-redactor/llms.txt`) - **OpenTelemetry Trace Redactor**: https://xvibelabs.com/tools/069-opentelemetry-trace-redactor/ (`https://xvibelabs.com/tools/069-opentelemetry-trace-redactor/llms.txt`) - **Postman Collection Token Redactor**: https://xvibelabs.com/tools/070-postman-collection-token-redactor/ (`https://xvibelabs.com/tools/070-postman-collection-token-redactor/llms.txt`) - **Stripe Webhook Scrubber**: https://xvibelabs.com/tools/071-stripe-webhook-payload-scrubber/ (`https://xvibelabs.com/tools/071-stripe-webhook-payload-scrubber/llms.txt`)
