Are there restrictions on the methods I can use to drive traffic to the Amazon.com site as compared to the [Amazon.co.uk, Amazon.de, Amazon.fr, Amazon.co.jp, Amazon.ca] Program?

Yes – participants in the Amazon.com Associates Program are not permitted to use paid search advertisements to send customers directly to Amazon.com or Endless.com. Other differences may exist, as the Associates Programs differ by locale. Therefore, you should be sure to read the Operating Agreement that governs the Amazon.com Associates Program closely before joining the Program to ensure that you can agree to and remain in compliance with its terms.
