Does WP Ecommerce have support for product variations which affect price? What I need is that for each product, the material (dropdown), the dimensions (drop down) and the finish (dropdown) will be used to determine the price for the product (and also the shipping cost). Customers may choose several products and each will have these parameters.
Is this too complex for WP eCommerce? And can it easily be linked to some kind of formal quote and invoice plugin and a Paypal gateway?
