A friend/colleague at the University of Louisiana/Lafayette met his first class of the summer term today. Since the class is somewhat "under-enrolled" he still does not know how much less than the usual $2300 for a short summer course he's going to receive. (Note: that's already less than we pay adjunct faculty per course at my university, and this colleague is a permanent faculty member.)
Update (July 10, 2013):
I just learned that my colleague will be paid $1500 for teaching this three-credit class to a small number of students. An adjunct at UNF would receive at least $2000, and likely more depending on how much they had been teaching for us.
