Free Advertising?

Hi Matthew,

There appears to be a bug in the home page advertising system. 3 days ago, I went to my system page and went to admin and clicked "advertise this system" and I chose the phrases and continued without making a deposit in an effort to finish my existing advertising which i had already paid for. So my advertising ran and finished yesterday. However I tried to advertise today again and I went to make a deposit and it says I have 1783 impressions remaining. I did not go thru with it. Please look into it and fix it. Otherwise, it looks like I can advertise for free. Maybe there is a promotion going on?
