This extension adds a new product type called Service to Magento. This product type is actually the Virutal product type but with custom logic modifications.

• The price of the Service is default 0.
• The price of the Service is defined by the user.
• The final price of the Service when order is placed, is the user-defined price PLUS a service margin.
• The service margin is configurable in the backend, per website.
• The shopping cart can only contain one service at a time.
• Services and other products may not be in the shopping cart at the same time.
