I have **two types** of product in my store - one is wines and another is food/ grocery. The shipping cost for wine is based table rates, while food/ grocery is based on a flat rate. So when you order a food from my store, I **don't** want to show you the table rates. And when you order a wine, I **don't** want to show you the flat rate as it is always at a lower rate. But when you order a wine and a food, then you get the **table rates**. So, how can I customize the Magento system to do this? Can this be configured in Magento? When I create a new product, I choose **Simple Product** as `Product Type` for Wines. What about food then?
