special shipping?

[kimber]

I would like to know if there is a way to charge additional shipping for particular items. I have it set up now that you get free shipping when you spend $40, but I am now offering custom painted larger items that are going to require special shipping. How do I override my original shipping settings for these few items?

How are you charging now for shipping?

Do these products have attributes?

If by charging by weight and you have attributes, can you add more weight to an attribute to offset the difference?
