When it comes to lumber, I'll usually call around, and if a local place has the same price, or a little higher, I'll go there. It's the same with hardware. If I need specialty hardware, I usually either go to ACE or TrueValue because the people there are more knowledgeable.
However, whether we want to admit it or not, we go to where it'll cost less, as long as the quality is the same. I'm not going to pay $1.19 for throw-away paint brushes at Lowes when I can get them at HF for $.29.
As for me and my house, we will serve the Lord!
