Just stopped at Lowes to look for rmp/zep. It (zep) was marked down to $4.50 gal. The clerk was in the process of pulling them from the shelf. She said they were either going to reduce the price ...
I was in Lowe's a month or so back and noticed that they had none (Zep) on the shelf where it once was. I asked a clerk who said he would check and get back to me. A little later he stopped me to say that they had discontinued selling it after several complaints and slow sales. He tried to recommend a new product they had, don't remember what it was, but I was not interested in buying, just looking around.
