For some reason, this lowe's is substantially more hopeful than their location in Tustin, ca. I had to run in several times as my buddy and I were working on my car.
The first time I ran in, literally, because we had already drained the oil from the car. We needed a longer adapter for a ratchet, and Rick, the Man, helped me locate several choices and even suggested one with a wobble which was very fitting as the bolt we were trying to reach is deep in the car.
The second time we came in on the same day, we needed butane because stupid sears didn't carry any even though they sell torches which use the fuel. This time, Rick, the Man, and his pal, Stephanie helped us out and she went to the trouble of looking up fuel burning temperatures on the computer.
The last time we went in, we had to just buy the propylene torch they carried because the stupid sears one was too weak.
I wish all hardware stores were this helpful!
