For sale here is an IPB perpetual license, this means you will receive free lifetime upgrades from IPB for all future versions of the software. I was originally planning on using this license for a project, however it never got off its feet.
Here are some pictures to prove that I actually own this license:

I'm looking for $130 for this license, which is a bargain considering that if you buy a new license you have to pay the $25 renewal fee every 6 months for support & upgrades. Contact me or reply here if you're interested.
