When processing a refund, the restock checkbox is checked by default. If merchants forget to uncheck it, out-of-stock products get incorrectly restocked, causing inaccurate inventory levels. Restock Blocker gives merchants control over restock behavior using three rules: a Global Rule to disable restocking store-wide, a Tag Rule for products with specific tags, and a Product Rule for individual products.

• Global Rule: Disable restocking for your entire store during refunds.
• Tag Rule: Block restocking for products matching specific tags.
• Product Rule: Control restocking for individual products with highest priority.
