Network-based grocery store

1. A computer-implemented method for fulfilling a plurality of network-based product orders in a warehouse using a wheeled cart, comprising:

storing, in a database, a plurality of network-based product orders each having a list of products;

utilizing a processing system to perform the steps of:

associating each of the orders with at least one of a plurality of order fulfillment spaces contained in a wheeled cart, each of the order fulfillment spaces including an actuable indicator communicatively coupled to the processing unit and configured to light up for viewing by a user of the wheeled cart;

receiving, from an electronic scanner communicatively coupled to the processing unit, data identifying at least one product to be retrieved;

receiving from the electronic scanner, data related to a scanned code associated with the at least one identified product to be retrieved for at least one of the plurality of network-based product orders, the at least one identified product located in the warehouse;

identifying a network-based product order including the at least one identified product associated with the data related to the scanned code;

transmitting a signal to the actuable indicator associated with the order fulfillment space corresponding to the identified network-based product order containing the at least one identified product with the scanned code, wherein the transmitted signal causes the actuable indicator to light up; and

receiving a signal indicating the at least one identified product corresponding to the identified network-based product order has been added to the order fulfillment space, wherein the signal causes the lit actuable indicator to turn off and is received from one or more of 1) the actuable indicator in response to the user actuating the lit indicator corresponding to the order fulfillment space containing the added product, or 2) the electronic scanner having scanned a bar code on a label associated with the network-based product order and corresponding order fulfillment space containing the added product.

2. The method of claim 1 , wherein the plurality of network-based product orders are grouped according to a subgroup area in which the products within the product orders are located in the warehouse.

3. The method of claim 1 , wherein one or more of the plurality of network-based product orders are subgroup orders, and upon fulfilling the subgroup orders, the subgroup orders are transported to a hub for aggregation with one or more other subgroup orders.

4. The method of claim 3 , wherein the one or more other subgroup orders are filled in parallel with filling the subgroup orders associated with the wheeled cart.

5. The method of claim 1 , further comprising providing an order label for each of the plurality of orders, each order label comprising a bar code associated with the products in an order from the plurality of orders,

wherein the data identifying at least one product to be retrieved is based on at least one scanned bar code from the plurality of provided order labels.

6. The method of claim 1 , wherein the scanner is cordless.

7. The method of claim 1 , comprising lighting an identification button in a bay of the warehouse corresponding to the data identifying at least one product to be retrieved.

8. The method of claim 7 , further comprising providing, at a display, a required quantity of the at least one product to be retrieved.
