How to remove your Amazon account
There is no immediate removal URL. You should send a message to Amazon (see link). If you actually buy at Amazon, do read the page well, about cancelling outstanding orders.

Helpful Trick: Removing online data
Publicly visible text/images often aren’t properly removed even when you succeed in removing an account. Try editing or removing them manually before removing the account itself. If you’re unsure what happens to your tracks: this can be found mostly in the Terms of Service/Privacy Policy; otherwise you can always contact Amazon and ask personally. By the way, removal requests don’t necessarily mean your data will actually be removed (e.g. due to legal obligations).
