I also like the convenience of round the clock access. Who knows, but I have not heard from anyone who had a bad experience. At least, not yet. I am more worried about handing my credit card to a waiter in a restaurant. To keep track of my expenses, I have decided to do all my shopping with one credit card which I use only on the Net.
Many people like to actually see and feel the merchandise.
This is important with apparel. However, for the items that I buy, I love to do comparative shopping. There is more to it than trying to save money. I like the convenience. I have used both Amazon and Barnes and Noble to buy books.
