Linking an AdWords account with Google Checkout?

The purpose of linking your AdWords accounts to Google Checkout is to earn free transaction processing. To link an AdWords account to Google Checkout:

• Sign in to Google Checkout.
• Click the Settings tab.
• Click AdWords.
• Enter your AdWords Customer ID in the box and click Request link. A confirmation email will be sent to the notification email address associated with your AdWords account. You, or the person managing your AdWords account for you, must follow the instructions in this email to complete the linking process. If you don't receive the confirmation email, please review our troubleshooting tips.

At this time, U.S. merchants may only link a Checkout account to an AdWords account denominated in U.S. Dollars.
