Other than editing the code directly, does anyone know of an add-on that can allow rule creation on a product. For instance, this product can only be sold in certain states so if you go to check out with that in your cart, it warns you that you will be unable to purchase it. Or, force the user to log in or register before adding something to the cart to run the check then so not to even add it to the cart if they are in a restricted state.
Thanks in advance!
