I am developing an e-commerce site using wordpress. This would be for a small print shop. There are products they are offering such as business cards or flyers.
When a user selects the business cards product, there are many options to customize it. For example the size, if it is bw or color, has print on both side etc. All these options are changing the final price.
I am looking for a plugin or theme that can do this kind of configuration and it is possible to customize these options for products or product types.
