Purchase, installation, and later use of tires are fine. Attempt to shop while tires were installed is difficult. Mismatch of time required, time of notification, time to shop. Then the issue of exiting the building with a cart of groceries.with payment receipt. There is no other way to deliver groceries to an empty car without having to walk on the busy roadway. As "scan and go" proctocol is finalized, maybe my plan to shop and install will be easier.
