$40 for a can of Freon? I think /not/.

i cant believe what you people are still doing in the U.S .
Its not 1975 any more you know !.Theres massive fines in Australia for "draining" R-12 . And now we have a carbon tax and the price of 134a has risen to $140 a kilo !!
Worst part is while ever this sort of stuff is going on , it wont make a single bit of difference
Australia is trying to save the world and will suffer the consequences !

There are massive fines in the U.S. also. But who is going to "catch" a individual.
All legitimate shops have recovery machines, and use them. I am a non legitimate shop and have recovery equipment, that I use.
One for R-12, one for R-134a, and one for any other refrigerants, and mixed/contaminated systems. Each machine cost over $3,000.
In the US it is still legal to use R-12, but it is not legal to make it or import it. I don't have all the facts on other countries, but I would bet China doesn't care about the ozone layer, as they are a large producer of R-12 among others.
