Many stores lose sales because shoppers can't add extras at checkout. Let your customers choose paid addons in the cart and cart drawer, shipping protection, gift wrap, premium packaging, eco offset, or packaging fee. Add each service as its own line item so pricing stays clear and fulfillment stays clean. Set prices, choose placement (cart, drawer, or both), add optional order tags or line item properties, and edit labels and styling in the Theme Editor with no-code.
