# Per-option Pricing

You sell computer systems. Your base model comes with an 8 GB hard drive. But customers can upgrade to a 16 GB hard drive for $100. With ShopSite, you can easily create unlimited configuration options (like hard drive, RAM, and monitor size)--each of which can increase or decrease the price of the product.
This feature can be used to sell special packages as well. For instance, your cordless drill costs $109, but when purchased with a drill bit set (value=$20) the package costs only $115. What a deal! Well ShopSite makes it easy for you to create this kind of an option for the shopper.
