There are many online food shopping sites（网址）. This is very surprising. Things like CDs, MP3, magazines and DVDs sell well online. But it is quite different to sell food online because people like to see food with their own eyes. It is very important for people to buy fresh fruit and vegetables. People like to choose their food by its color. They also want to feel and smell it. But some people like to go to the same shop to buy food, because they think the food there are very good. So if the food is always good, they may also feel comfortable（舒适的） buying it online.
Boxes of fruit and vegetables have been delivered（运送） to homes around Britain for a few years now. Dried or canned（罐装的） foods are almost always the same, but things like apples are not. People may want to choose their own apples so they can take the ones that aren’t bruised（碰伤）or the ones that look nice. Buy dried and canned food online is easier. A person can buy this kind of food on the Internet and then buy fruits and vegetables at a store or a market.
Now people can also buy food through supermarket websites. There people can find most of the things that supermarkets usually sell. Other food websites sell different types of food. Some sell food from one part of the world, such as Asia and Africa. Others sell food that is hard to find in supermarkets. There are also websites that sell foods, such as cakes and candies.
The food is usually delivered by the next day or even on the same day. People still need to be careful, though. They must check to see if the food is fresh when they get it. It is a good idea for people to find out how far away the food is being sent from. It is also a problem if the company does not use refrigeration（冷藏）when they deliver food that should be kept cold. If traveling a long way in summer to deliver the goods（货物）, this is important.
