Actually Grandad, now that you mention it, I do almost all my bill pays online. I have a few that still come hard copy paper but that is only because the organizations have not yet gone 'online' i.e. our city doesn't allow you to pay property tax online (yet).
I also research things I buy and I have to say the bulk of my hard item type purchases (camera, kindle, UV filter and Air purifier) have been done online. The stores here do not carry much in stock so essentially you end up going into a store here, buy the item and then they order it online have it shipped to them requiring I go back and pick it up. MUCH easier for me to skip the middle man and make the purchases and orders direct.
I can actually see that the days of the big box stores are limited. Years and years ago we had SimpsonSears Store which put out huge catelogues every year. Then the "Simpson" half disappears and Sears was the primary store here. You perused the catalogue, went into the Store Front and made your purchase which was then ordered and brought to the store for you to pick up. Can't say that process has changed dramatically here.
I too would be lost without the internet AND without the internet I'd hazard you and I would NEVER have talked!!
I can see that the Internet might make hand writing - the writing not printing - redundant into the future and I'm not even too sure about printing either.
