Personally, I think that online shopping is important nowadays, because it is easier for people to order things without going anywhere. I don't order clothing items simply because I can't try them on. But I do order books and stuff like that. That's why I like this way of shopping, it's timesaving.
One plus of online shopping is that you save time, I have mentioned it in the first paragraph. Another one is that if you order food for example you don't have to go far away to get it. While you wait for an item you can do other important things you need to do. The minuses are that you don't know the quality of an item, and, if we speak about clothing, whether it suits you. For example, you have your food chosen for you so you don't know if it's fresh or not.
I ordered a comic book some time ago. I clicked on a bookstore and searched for the one I wanted. Then I clicked 'buy now' button and proceeded to the form where I had to fill in the address and my credit card number. Then it was done!
That's all what I wanted to say
