The shopping carts with chips that lock the wheels when trying to leave the store are a terrible idea. One needs the shopping cart loaded with a week’s groceries for a large family to get the bags to the car.
Here in the suburbs some stores have set the carts to lock at the edges pf the parking lots and it works. But stores such as Moisha’s depend on on street parking and shoppers need to be able to wheel the purchases all the way to the car.
Other models that work successfully in non-urban markets include:
A system where your purchase is placed in a bin on a conveyor in the front of the store, you drive up, hand the box boy your ticket and they load the car.
A system used by the Market Basket Chain in Massachusetts and New Hampshire: they hire mentally challenged young adults who wheel the carriage out to the car for every customer, help unload and then return the carriage to the store.
These cost money and do raise prices slightly.
