Ad Muncher free through Thanksgiving
 

Head on over to Giveaway of the day, then follow the link to register your free copy of ad muncher. The deal is popular and the site is being slammed, so the developer agreed to keep the registration link open for an extra day.

It took a few tries for me to get through but it's worth it. Best Ad-Blocking tool out there - period.
