Recharging a/c, went to O'reillys and was told 134 was $18/can. Wife went to Walmart and I called here to see if they had any. Got call back, all you want for $4/can. Just had her get 4 as I was leery about what it was. Yep, good old R134. Did have to go to AZ to buy the little adapter that all the new cans of R134 require. Only $3.00. Seems like a good deal to me!
