Patent ID: 8341036

Claim:
A computer-implemented method in a client system for ordering items, the method comprising: receiving, from a server system, by a computer of a client system a client identifier of the client system; persistently storing the client identifier at the client system; and for each item of a plurality of items: providing for display, at the client system, information identifying the item and an indication of a single action that is to be performed to place an order of the identified item, wherein the single action is an only action required by the client system to complete the order of the identified item without requiring the client system to confirm the order following performance of the single action; and in response to the single action being performed, sending to the server system a request to order the identified item and the client identifier, the request to order being a single-action order request indicated by the single action and the client identifier identifying account information of a user; wherein the sending causes the server system to determine how to combine and to combine into a single order the single-action order request indicated by the single action and one or more previous single-action order requests associated with the client identifier.
