Some recent threads have indicated some members have picked up GC at $1/quart. I went to AutoZone yesterday and it was $3.99/quart. I went to another AutoZone today and I saw some little green men (Elves?) shaking their heads. They refused to talk to me. This AutoZone had no GC on the shelves. I had a clerk check in the back but they were out. I went to another AutoZone an it was $3.99/quart. What is going on? Is Castrol about the pull the plug?
