About MarginLock

Aggressive discounts and bundles can quietly sell products below cost. MarginLock is the guardrail: set a minimum margin, and any cart that would fall below it is stopped at checkout, before the money is lost. It checks each variant's margin in real time with a native checkout-validation Function. Choose block or monitor-only mode, and decide how to treat items with no cost data. A per-variant table shows cost and a live margin on every line. No theme code.
