It must be where you live. We still have a milk man that comes twice a week (farm eggs too) although it's a transit van now, rather than a horse and cart. A few farms that have vending machines and glass bottles, it's farm milk but the vending side of it seems to be a company that runs the chain. Then each farm has a selection of other items, such as eggs, butter, honey.
We also have a lady that delivers fish and game on Fridays and a village with two good butchers in it. No local fruit and veg though.
Here's a do you remember delivery? The soft drinks man? Lemonade, Limeade, Orangeade, cream soda, no cola as far as I can remember though. We had Corona.
