Based on the requests to integrate the Google Checkout payment system with Yahoo! Stores and Merchant Solutions, we have developed a solution that allows Yahoo! Store owners to give their store owners the option to pay for their order through Google Checkout.
Our solution to integrate Google Checkout with Yahoo! stores has had to compromise functionality to ensure that Yahoo! store owners do not enable a solution that might lead to their store being terminated by Yahoo!.
Our Google Checkout system places the "Pay with Google Checkout" on the order confirmation page which is displayed after the customer places their order through the Yahoo! Shopping Cart. If you place the Google Checkout payment button on the shopping cart page or on another page before the customer places their order through the Yahoo! shopping cart system then you will be violating the Yahoo! Terms of Service which could lead to your store being disabled by Yahoo! (http://store.yahoo.com/guide.html
"Merchant Guidelines" #6)
While we do not feel this is the best solution possible to integrate Google Checkout with Yahoo! stores, we do feel it is the safest solution to ensure your Yahoo! store is not terminated by Yahoo!.
You can purchase the Google Checkout integration for your store here..http://www.thesupermanager.com/google-checkout-gbuy.html
