best way to promote a product if you have a small budget is honestly to say is myspace. i has over 300 million registered users. you just have to contact the right people :). It is pretty tricky thing to get into but if you have right software and course it is pretty easy ounce you get started. i started myspace until i invested in Jv deals promoting affiliate products
best ways to get into the myspace world of marketing would be with the course of myspacecashmaker dot com ofcourse since as you can see he has been getting alot good reviews on the net about how his is only proven system to work. and to use the program buddpromoter dot com to boost it up a tab. since most programs now do not manage more then one account at ounce when buddy can manage 500 accounts at same time.
I will do a follow up when i find out more info on promoting but i hope this helps you newbies out there.
