I have always been able to consistently advertise online without payout a whole lot of money out of pocket.
The secret of course is to promote your ad sources to your team, earn from that and build up your advertising budget. You MUST be consistent with you online advertising. Post every day!
I've been able to do this with several sites.
For instance, I consistently earn $100 plus each month with my Aweber autoresponder. That's just one resource...
I try to upgrade on ad sites, depending on how effective they are and then I will recommend them to my team. I recently joined a new ad site that just launched, only cost me $1 and I actually do get traffic from it.
The best part is that I also earn from that, even though it only cost me $1 and never another cent out of pocket, and I'm building up my advertising budget for more traffic! It really IS working!!
