Surcharly lets you sell extended warranties, protection plans, or any add-on directly at checkout. Each offer appears as a selectable item showing its title, image, and price; buyers add it with one tap, always explicit and never pre-selected. Create multiple offers in the app, show them on all carts or only when specific products are present, and limit each to one per order. The add-on is added as a real line item, so it appears on the order for fulfillment. No theme code and no customer data

• Buyers opt in with explicit consent, never pre-selected or auto-charged
