Yes. For Returns/Refunds, I’d put a clear final-sale policy in Shopify.

Return & Refund Policy

All sales are final.

Southern Tool Deals does not accept returns or exchanges for change of mind, buyer’s remorse, ordering the wrong item, or deciding the item is no longer needed.

We describe each item as accurately as possible, including whether it is new, open-box, used, refurbished, or otherwise noted in the listing.

Shipping charges are non-refundable.

Any manufacturer warranty, when applicable, is subject to the terms of the manufacturer.

This policy does not limit any rights a customer may have under applicable law.
