Kinda the same storey here.
We have 5-6 HD's in a 20 mile radius, not sure if any of them are in trouble, they all get pretty good business.
I opposed Home Depot when they first started popping up, use to call them Home S#*tpot, they did force a couple local yards to close down, wasn't to happy with that, but now I like Home Depot and rely on them to help me run my small contracting business, I do all rough maintenance/restoration type work, don't do remodeling or building so I'm not buying home building materials/furnishings, but more of maintenance materials, supplies, tools etc etc.
I use them as a huge well stocked hardware store with a good selection and decent prices, I shop mostly in an urban demographic store, probably the slowest one around so I hope this one doesn't close, the associates are not the most knowledgeable but are very polite, I know many of them by name and I know the store like the back of my hand.
For my own building/remodeling projects at home I will buy some utility type home furnishings like lighting, electrical fixtures, plumbing supplies etc. I'll buy their plywood but I don't like the quality or price of their heavier framing lumber.
