Stop ads from following you around the internet

Stop ads from following you around the internet. Sometimes I've already bought the product so it's even more annoying. AKA Remarking, Retargeting, Online Behavior advertising,

Update 10/15/2016: Another opt out. This one will stop your Amazon viewing from following you around the internet: https://www.amazon.com/adprefs/ref=dra_a_ms_hp_hn_xx_P3378_100

Update 10/24/2016: Another site to set opt-out preferences (it just set 106 opt-outs for me today): http://www.aboutads.info/choices/
