Their policy says:
You may not purchase products during sessions initiated through your own Associates links and will not receive referral fees for such orders. This includes orders for customers, orders on behalf of customers, and orders for products to be used by you, your friends, your relatives, or your associates in any manner.
Please go to affiliate program amazon help and you will find this policy rule there.
(They don't even allow me to post the affiliate link here.)
Don't risk your affiliate status by clicking on any of your own ads-- or even those of other hubbers.
