What’s up with R134 prices?

Was working but not cold.

Tried the "Enviro-".

Did have gauges attached to both ports.

Ran for about 10-15 minutes before it purges it's self.

134a made it better than it was before I tried the other but still not super cold.

I found it very odd.

Sometimes Chryslers, more than any other brand, exhibit "personality" traits.
