I don't openly boycott stores and make a fuss about it, I just choose not to spend my money in stores that support this kind of perversion. I don't eat at a certain fast food restaurant for the same reason.
Local chain home improvement stores are worth looking at. In my neck of the woods it’s Menards. Elsewhere there are places like 84 Lumber. Visit the yellow pages (physical or online) and look for home improvement stores. The selection is often considerable when hometown establishments are included.
