Carrier restrictions for carts containing certain products

[ajensen27]

I have some products that I ship internationally while I have others that I don't due to weight and size. For those products, I have it selected in the product under "Shipping" only my U.S. shipping carriers.

 

The problem I have is that if a customer say in Europe is ordering a product that I ship internationally and a product that I don't, it still allows them to place the order and then it will split the order in to 2 orders. For the split order with the item that doesn't ship internationally, it doesn't give the order a carrier (so no charge for shipping) but then it still charges the customer for the product.

 

If a customer has a product in their cart that doesn't ship internationally, no matter what else they have in their cart, how can I make it so that they can't place the order (no carriers will be listed)?

 

Please help! Thanks!
