The present systems and methods describe a computer system that collects user shipping preferences, including, for example, the shipping speeds (e.g., standard three to five day shipping) a user selects on various retailer websites. The system is configured to determine the one or more preferred shipping methods for the user based on the collected shipping preferences and to save the preferred shipping methods to memory (e.g., the user commonly prefers standard shipping). When the user visits an online retailer, the system, detects a shipping field (e.g., where the user may select or input a shipping preference), accesses the saved preferred shipping method (e.g., the user prefers standard shipping), and populates the shipping field with the saved preferred shipping method (e.g., the system automatically selects “standard shipping” for the user).
