For many enterprises, an e-commerce application is part of today's web appearance. There is a virtual standard in this area for Mambo, Mambo-phpShop. phpShop (which changed its name to VirtueMart while the book was in development) has proven itself very well in practice and in the context of our projects. It must, however, be stated that a shop is not simple. One can guide a user in various ways in a shop, but only few are successful. The appearance, of course, plays a huge role. This chapter attempts to get you off to a good start. Your own ideas and conceptions will soon play the most vital role.
