In some cases, you may want to disable specific products from being purchased via Google Checkout. The reason for this is because Google Checkout doesn't allow some certain types of items to be sold. To disable a product from Google Checkout, you may do the following:

1. Login to SEO-Cart and go to Store->Products. Modify the product you wish to not accept Google Checkout for.
2. Scroll down to the "Google Product Settings" section and enable the checkbox for "Disable Google Checkout for this product".
3. Click the update button towards the bottom right corner of the screen and regenerate your store.

If any non-Google Checkout items are added to a customer's shopping cart, the Google Checkout option will be disabled for them.
