I have a configurable product, where the simple products have different stats (i.e. some have no VAT), so when it comes to checkout, I need the simple products to be in the cart to show the differences.

Is there a way to pull the simple products from the Configurable when the customer adds the configurable item to the cart?

Additional info:
Magento ver: 1.7
Plugin using: Magento Mechanics Products Grid

I would use the observer, sales_quote_item_qty_set_after

And check if the configurable product exist in the cart, some information here.


And after that, remove the configurable product from the cart. And add the simple product.
