mp_dynamicpricing 0 is the command to disable dynamic pricing. (currently playing gungame so I cant buy anything to see if it's enabled or not).
I think I'm in a similar situation to Killa_S. My school schedule has been ridiculous, I have midterms every 5 weeks, and then finals every 5 weeks. So, basically every 2.5 weeks I have midterms or finals, for 2 different courses.
I enjoy the same maps for the most part as Whon :)
