Depends on WHO does the work.
I have a 609 certification(I can buy R-12). About a week ago I paid $28.00 for a 12oz. can. This was a jobbers rate - off from $35.00.
I hear people around my neck of the woods saying that garages are charging $75.00 - $100.00 for a lb. of R-12. Some charge less. Again, it all depends on who is doing the work.

James Madison - Oppressors can tyrannize only when they achieve a standing army, an enslaved press, and a disarmed populace.
Liberty Firearms Training - After years of trying to regulate California criminals with a never ending stream of gun control laws they have still not given up with the belief that if they make something a crime that criminals will miraculously start obeying the law.
