7. The method of claim 1, further comprising:

providing by the websites system a website accessible by the user for receiving inputs from the user to perform at least one of the compiling step, identifying step, and displaying step.

8. The method of claim 1, further comprising:

reporting an optimization failure to the user if the optimizing step does not produce an optimal shopping order.

9. The method of claim 8, further comprising:

repeating said optimizing step until an optimal shopping order is produced; and

notifying the user when the optimal shopping order is produced.

10. The method of claim 1, wherein the optimizing step is performed off-line, and the method further comprises:

notifying the user with a notification message when the off-line optimizing step is completed.

11. The method of claim 10, wherein, in the notifying step, the notification message is communicated to the user using one of the following:

an e-mail, a pager, a phone, a facsimile, and a PDA (personal digital assistant).

12. The method of claim 10, wherein the notification message includes a unique identifier to be used by the user to access the optimal shopping order through the website system.

13. A computer program embodied on computer readable media readable by a computer system, for providing online comparison shopping from among two or more vendors, the computer system being a website system accessible by a user through a communication network, the computer program product comprising computer executable instructions for:

compiling a shopping list identifying specific items to be purchased;

receiving optimization criteria specified by the user;

optimizing, by the website system, the shopping list based on the optimization criteria to produce an optimal shopping order, said optimization criteria being applied to offerings of said specific items made by at least two of said two or more vendors;

displaying the optimal shopping order to the user;

receiving the user'"'"'s modifications to the optimal shopping order;

receiving a request from the user to perform only a recalculation of a total cost for the optimal shopping order;

recalculating, in response to the user'"'"'s request, the total cost for the optimal shopping order based on the user'"'"'s modifications to produce an updated optimal shopping order; and

displaying the updated optimal shopping order to the user.

14. The computer program product of claim 13, further comprising computer executable instructions for:

receiving the user'"'"'s modifications to the optimal shopping order;

re-optimizing the shopping list based on the modifications to produce an updated optimal shopping order; and

displaying the updated optimal shopping order to the user.

15. The computer program product of claim 13, further comprising computer executable instructions for:

receiving an acceptance of the optimal shopping order from the user; and

processing the optimal shopping order in response to the receipt of the acceptance from the user.

16. The computer program product of claim 15, further comprising computer executable instructions for:

receiving shipment tracking information from multiple vendors for all items identified in the optimal shopping order; and

displaying the shipment tracking information to the user.

17. The computer program product of claim 16, wherein the shipment tracking information identifies a plurality of different tracking numbers corresponding to the multiple vendors'"'"'shipments of all items identified in the optimal shopping order.

18. The computer program product of claim 16, wherein the optimization criteria include at least one of the following:

the lowest total cost including shipping and sales tax for all items identified in the optimal shopping list, vendor preference, vendor dislikes, a user-preferred shipping method, the fastest delivery time for the all items identified in the optimal shopping list, item availability, total order cost, and price range.
