If you're planning to purchase traffic, I suggest you choose carefully who you purchase it through. I purchased 125,000 unique visitors at SubmitPro.us for one of my sites. They were supposed to filter the traffic to me over a 30 day campaign. Instead, they dumped 120,980 hits on my site in a single day! Needless to say, my bandwidth was quickly consumed and my site was down for the remainder of the month.
I never did get the balance of the traffic that they owe me, but who really cares. Of the 120,980 hits that they sent, none of them stayed on my site for more than a couple seconds. Personally, I don't think they were really "unique visitors", but were automated hits through proxy services.
On the "up-side", they dumped all those hits on me with only 4 days left in the month, so my site wasn't down for too long a time. It was a learning experience that I'll never make the mistake of taking part in again.
