Can you buy through your own Amazon.com affiliate links?

The answer is no. I have heard varying answers to this question, so I decided to go to the authority on this one, Amazon.com. In their affiliate agreement, they explain it quite clearly:

You may not purchase products during sessions initiated through the links on your site for your own use, for resale or commercial use of any kind. This includes orders for customers or on behalf of customers or orders for products to be used by you or your friends, relatives, or associates in any manner. Such purchases may result (in our sole discretion) in the withholding of referral fees and/or the termination of this Agreement. Products that are eligible to earn referral fees under the rules set forth above are referred to as "Qualifying Products."
