ShipRules: Combine Orders

ShipRules: Combine Orders is an app on Shopify that allows merchants to merge a customer's duplicate orders and ship them only once. It helps in saving shipping costs by combining separate orders into one shipment. The app finds fully paid, unfulfilled orders from the same customer to the same address within a set time window, merges them, cancels duplicate orders, and refunds the extra shipping costs. Merchants can choose to approve each merge manually or set up automatic merging using Shopify Flow. The app also provides a log of every merge for tracking purposes.
