Centering Amazon New Amazon Link Builder

I have been trying to center the "product ad template' for about 1 hour now but I don't know how to code.

Anybody used this yet and know how to center the ad template inside my post?

I will give $5 worth of bitcoin to the first person who can help me without me having to give out my url to anybody.

If you're just making a post on Wordpress or something then I think <center> before the ad and </center> will center it perfectly.
