Add product as a case - Query

[bruce.flexi]

Hi,

Was wondering if you guys can suggest something on this.

I need to have to 'Add to Cart' button on the product details page - 1 will be a normal 'Add Product' button, another will be a 'Add product as case'(in this, we can add a set of products, maybe 6 or 8 for a predefined price). How can i do this in Virtuemart 2.0? Is there any module or something that I can use to implement this?

Thanks,
Bruce
