Placing a purchase order using one of multiple procurement options

A computer-readable storage medium whose contents cause a computing system to order an item, by performing a method comprising:

• providing for display information identifying the item and an indication of a single action that is to be performed to order the identified item, wherein the single action is an only action required by a user to complete the order of the identified item;
• providing for display in a multi-procurement ordering section a current procurement option associated with information related to supplying of the item, wherein the client system displays enough information about the current procurement option to allow the user to uniquely identify the current procurement option, without making the current procurement option identifiable to other users;
• in response to receiving an indication that the single action has been performed, initiating ordering of the identified item using the information related to supplying the item associated with the current procurement option;
• and
• in response to receiving an indication of whether the user has selected the indicated option so as to affect the supplying of the item, sending to a server computer a request to order the identified item, thereby resulting in fulfillment of the order.
