Hi
I was wondering if i sign up to amazon associates does that mean my site is signed up to amazon for life. i mean can i remove the link to amzon if i ever feel like it

second i was wondering if i can use the link on my site for me to purchase stuff too.
i
what i mean is go to amazon through my site, so that if i buy something from amazon, i wil get some credit to my associate account.
