I just stumbled upon this over at Taylor and Francis (publisher for Australasian Journal of Philosophy).
Their plan is called iOpenAccess. They will make any articles that you publish with them freely available to the public, but…
All authors whose manuscripts are accepted for publication in one of these iOpenAccess journals will have the option to make their articles available to all via the Journal’s website, and to post to repositories, for a one-off fee of $3250.
Here’s another option. Publish your article with a genuinely free and open access journal. Don’t pay them anything. Have your work be freely available.
