And anyone with any sense would have most online purchases shipped to their work address instead, negating your last paragraph.
I tend to use public transport where needed or walk into town - much better than trying to find a parking spot and then panicing about some uppity parking inspector issuing you with a fine. It then lets me use physical stores as a good way of previewing items then redlaser'ing them to find the better prices online. If the price in-store ends up being cheaper than the online price + delivery I'll buy there and then.
I also find home delivery of the bulk of our food to be handy since I don't own a car and don't really want the sheer cost of running and insuring one, any extra treats or things we run out of in between can be easily picked up from the nearest shop to us.
The only thing online shopping can't compete with is when you're walking around a physical store and you spot something you didn't even think about or is new and you want to give it a go, especially if it's an item that would normally fall out of the behaviourally tracked suggestions used on websites.
*shrug* To each their own, while I overwhelmingly prefer online shopping I find use in physical stores from time to time too.
You know what would revive high street shopping? Decent, cheap public transit and a scheme to lower the cost of rents so small chain and boutique shops could return. Just need to find a way of taking the likes of DSG stores and FirstBus round the back and giving them a sympathetic twin barrel to the side of the head ;)
