Pre-purchase feedback apparatus and method

A computer system comprising:

• one or more processors;
• one or more memory devices operably connected to the one or more processors;
• the one or more processors and one or more memory devices forming a computer system supported by and proprietary to a retailer;
• and
• the one or more memory devices collectively storing
• a shopping module programmed to receive via a first computing device an instruction to share with a second computing device data describing a proposed purchase of one or more products,
• a communication module programmed to pass the data to the second computing device piecemeal such that each product of the one or more products is passed to the second computing device in real time as that product is (1) checked off a shopping list on the first computing device or (2) scanned by the first computing device,
• the communication module further programmed to receive via the second computing device a request to add or remove at least one item to or from the proposed purchase, and
• the communication module further programmed to pass the request to the first computing device.

A computer-implemented method for enabling pre-purchase feedback, the method comprising:

• supporting, by a retailer, a software application and a computer system that are proprietary to the retailer;
• storing, by the computer system, information linking a first instance of the software application to a second instance of the software application, the first instance being installed on a first mobile computing device, the second instance being installed on a second mobile computing device;
• receiving, by the computer system from the first instance, an instruction to share with the second instance data describing a proposed purchase from the retailer of one or more products;
• passing, by the computer system, the data to the second instance piecemeal such that each product of the one or more products is passed to the second instance in real time as that product is (1) checked off a shopping list on the first instance or (2) scanned by the first mobile computing device into the first instance.
