Audio sets are priced at $5 per hour of lecture. Prices are reduced (5-10%) for compilations, as well as in special cases, where: 
- The audio quality is sub-standard
- Essential handouts are missing
- Part of the lecture is missing (if the original master was damaged, corrupted, or degraded)

Video sets are sold at $8 per hour of lecture.

Classes are generally $15 per hour, although this is not guaranteed. Price is affected by many factors, so pricing is subject to change. Also:
- We charge a $15 administrative fee for processing Continuing Education Credits
- Students are able to register for classes at a discount
