I am offering some of the best banner ad space deals at
https://bitcointalk.org/index.php?topic=934291.0 The best offer is a LIFETIME banner ad package where you will be able to promote any two 728x90 banners on my bitcoin related website and they will be on EVERY high traffic area on my domain. Even if I make a new high traffic area, your banners will be there!
You can get the LIFETIME package with only payment of 1 bitcoin (see above link for payment addresses)
You will own the two spaces and you can do anything you want with them...
You can use the spaces to promote any referral banners or promote your websites.
You can rent out the space to others and keep all the profits!
You can change the two banners unlimited times just by contacting me with the new banners.
Let me know if you have any questions and I will be happy to help.
