Since were all sitting at a computer and have access to the tower website I think it is helpfull to post this. This link is always located at the bottom of towers mainpage. You have to scroll down to see it..

http://www.towerhobbies.com/promos.html

It is the Tower Website that lists most if not all of there current promos to the general public. If you have paid to be a SuperSaver member you get your mailer. Also If you recently made a large purchase you may get special promo. But I think that your account is flagged when you are sent a special promo. This is to ensure that people don't do what it sound like some are trying to do..
