Yes, I sometimes order a something over the internet. Usually it is books, films, gifts and so on. It’s easier than going to the shops, which is not close to home, and then carry this things home. It is easier to order all what you need to home.
To order in online shop, first of all you need to have an account in this online shop, I think, than you need only to find and choose necessary products, to form a final order, specify when, where and how to deliver it to you. Also you need to choose method of payment and wait. After some time you will get your order quickly and easily.
