Here in the US all the big supermarket chains offer either a drive-up service (where you drive up and park, and the order will be brought out to you and loaded into your vehicle), or full delivery to your door. As a single parent this service has been absolutely wonderful. It saves me at least an hour a week, and keeps me from impulse buying and blowing my budget. I can schedule the delivery for a one-hour window when I know I'll be home, and the quality of the produce has been excellent. I pay a yearly fee for unlimited deliveries (I only use the service once a week), and typically about a $10 "tip" to the delivery driver each week.
