Per-item fees that hold through checkout

Feelock attaches a fee to individual products in the cart — handling, recycling levies, surcharges — using Shopify Functions, so it stays with the line item instead of being discounted away or appearing as a surprise at checkout.

Install Feelock from the Shopify App Store, then open it from your store’s admin.

• Per-item product fees. Attach a fee to any product. It is applied in the cart, so the customer sees it on the line item they are buying rather than as an unexplained total at the end.
• Fee-safe discounts. Run discount codes against the product price while the fee stays intact, so a sale does not quietly give away the part you are obliged to collect.
• Payment surcharges. Add a surcharge tied to the payment method the customer chooses at checkout.
