Google Checkout Program policies state that you may not accept payments through Google Checkout for the sale of any prohibited items as defined in the content policies So for the sellers' convenience MagneticOne added a special option, extra field to each of your products named " Accepted by Google Checkout " that is blank for all products by default. The default blank value means that the product is accepted by Google Checkoout. NO changes need to be made to allow Google Checkout for a product.

If you have the products that are in the list of prohibited items as defined in the content policies you need to disable them. It can be easily done by entering  No in the "Accepted by Google Checkout" field. You can check if the product is accepted or not by adding it to the cart. Google Checkout button will be grayed out in this case.

Please note that if multiple products are added to the cart and at least one of them is not accepted by Google, the Google Checkout button will be grayed out as well
