Buying banner space

[Jay81]

Hi,
I wonder if I can buy banner space to place my ads in from specific websites?
I know you can place your add in specific sites via Google display ads.

But is it cheaper to purchase banners elsewhere? Network? Direct from the website?

If anyone has experience in this please chime in.

Cheers

Jay

Cheaper? how many million impressions
Best bet are ad networks ... the most inventory. Direct webmaster to webmaster media buying is rare ...
