I have just unpacked and put away my groceries which were delivered to my kitchen table. I remember Mum getting groceries delivered when I was a child so it's not a new idea. Her groceries were delivered in cardboard boxes which would be used several times over. See, even the concept of recycling has been around for a long time.
When I was a young child many food items were home delivered, depending on where you lived. The baker would stop on the main road near my Grandma's house. Grandma would go and buy bread from him and pop it into a strong plastic bag she kept for this purpose. Some people got milk and meat delivered. In the city you could get soft drink delivered.
I don't think there was ever a charge for delivery of groceries back then. (Let me know if I am wrong.) The amount charged for delivery these days will vary with the day and time. Delivery for the first order is often free. Sometimes delivery fees can be avoided by buying groceries to a certain value or having them delivered on a particular day. There may be other special offers which enable a shopper to get free delivery.
Shopping for groceries online can be convenient, especially if you don't have a car. About a decade ago I didn't have a car, as is my situation now. Then I would go to the supermarket, do my shopping and either arrange to have it home delivered or else I would catch a taxi home and take my groceries with me. I still had to go to the supermarket.
I find shopping online more convenient. There is no wandering up and down aisles. I don't have to line up at the checkout, kicking myself for choosing the busiest time to shop. I can place my order online at any time of the night or day and drink a coffee while I do it.
The first time I placed an order online it did take me a long time. I kept thinking it would have been quicker to drive to the supermarket, if I still had a car. It took me ages to work out which category some items were listed under and there were a couple of things I never did find.
Each time I place an order it takes less time as I am more familiar with the system. Now the majority of my frequent purchases are in my online lists which speeds things up.
I do like to see some items before I buy them. Sometimes it is good to be able to see and compare. There are a few things I will probably continue to buy in person when I walk to the shops. I live near a weekend market where I can buy fruit and vegetables. This enables me to choose the freshest produce and I enjoy chatting to the stallholders. However, for most of my shopping, especially heavier or bulkier items items, I will be using online shopping.
Online shopping wouldn't suit everyone and isn't available in some areas. However, it has its advantages and I am finding it useful.
