I find these promotions VERY easily because I use a software program called OTC View. The company that makes this software just opened up last November and they have been working on their product for about 2 years now but have just made it available late last year.
This program is absolutely amazing. If you want to get the exact same information I do, I suggest you visit their site http://www.otcdynamics.com and get their free trial - there is no cost at all for the first 14 days.
OTC View is one of the best screeners I have seen in years.
