I look at sites to see the reviews and what other people think about the product, especially if it's expensive. I then go to the store to purchase, so I don't have to pay for shipping and can have it that day.
Internet shopping is a lot safer. I've been out on Black Friday. It's not pretty. A guy even got trampled to death at Wal-Mart.... At least, that's what I heard on the news. We only went to Target, but it was still nuts.
