I just ordered everything to completely replace my A/C system and need to get some 134a now. I work part time at a parts store and we have 12oz cans from $20-$12, but then I look at the stuff at Walmart and it's around $4.50 a can.
Is it all the same stuff, or is the expensive stuff better for cooling? I only want to do this once, so I'm attempting to do it "right".
