AMAZON - your affiliate links on other websites?

Just wondered if anyone has had experience of running multiple websites with ONE amazon associates account. So same ID to all websites.

Do I break the rules by doing this? Do they check wheter or not I have products on a few sites with same ID??

you can have as many tracking ID as you want from your single amazon associates account.

i only have 1 associate account but many websites.
haven't faced any problem
