The years when it would have been impossible to envisage being able to order such a full spectrum of products from the comfort of your own home for delivery there the following day. The number of van deliveries on a daily basis to houses in our small housing estate of average affluence seems to me to have reached a level little short of being phenomenal.
Mail order, yes, but we had many vans and deliveries coming down our middle class road and back lane in Newcastle in the 1950s.
3 different milk men Monday-Saturday mornings. Newspapers next, delivered from 2 newsagents every morning and evening followed by 2 postal deliveries a day. I can think of 4 different laundry company vans calling weekly, plus Collars Ltd for stiff white collars. The fish man. At least 3 butchers and two fruit and veg merchants, one still with horse and cart, the other from an army surplus Bedford truck. 3 or 4 firms of coal merchants in the back lanes who'd collect from our nearby railway station yard. And the rag and bone man with his cry "Any old rags or bones or lumber" I think that was what he was trying to say but you couldn't be sure.
Then there were all the bigger delivery vans from the department stores like Fenwicks, Binns, Bainbridges, Farnons etc. Our parents would select in the shop and request delivery with payment on their monthly account.
Home telephones were becoming more common so much could be ordered that way - no passwords or security needed. (The local bank probably wouldn't request security either, they knew their customers personally back then!)
Of course back then if you wanted to phone a friend, or a shop, you'd look in the the telephone book/s (every telephone box had one) or called free directory enquiries. Back then having an ex-directory number was rare.
We got by and the roads were a lot less crowded.
