Know what you want and where it is cause help is hard to come by. I like the fact that they have nearly everything for home improvement projects but dislike the fact that finding someone to help you is kind of like playing Zelda. The work you have to go to in order to get help is crazy. I went in to look at purchasing some pipe for a project along with some concrete and plaster. The person that I finally found that "worked" in that department didn't seem to want to help and looked at me like I was crazy in what I was asking for. I may not have known what it was but he could have been a bit more helpful.
