Wordpress OTO (WP One Time Offer) Plugin
After needing a plugin that would make "real one time offers" and not finding one worth a darn, we decided just to make one. It turned out so good, we just had to release it to other WordPress heads like yourself. If you understand how to create a page with the built-in WordPress editor and can follow simple video instructions, you can setup your first OTO within 15 minutes after installing this plugin.
