There still are so many websites that do not have their own shoppingcart. It does not really matter if an online store has a cart or not if you are not a frequent shopper. But for a person who shops for so many things in the internet more often than not, it is important that a website has its own shopping cart. It makes shopping so much easier for me. So whenever I see that a store does not have its own cart, I always hesitate. If another store is selling it and can provide me better service, then there is no reason for me to buy it anywhere else.
