A method and system for interactively shopping for groceries, especially on an Internet web site, where the user may create a shopping list, shop for items from the list at a selected grocery store, arrange for pick up or delivery of the selected items, and provide payment. A user may also download a created shopping list to a handheld computing device (e.g., PDA) or print the list with reference to the layout of a particular grocery store. Users are required to register and provide specific demographic information (useful to manufacturers and stores) to be eligible to receive the benefits of use of the web site, such as menu creation, coupon downloads, menu planning, and recipe input. Shopping lists may be created from a single input screen using standard language text. Products may be automatically suggested to the user based on best regular price or retailer's specials. Recipes may be altered to meet numbers of servings or to comply with dietary requirements.
