I agree it is a slippery slope. My thoughts would be different if he was actually Mr. HD, and was padding his wallet directly. This young man probably works for minimum wage (only an assumption, nothing more) and is using the resources of the store he works at to provide a valuable asset to DIY'ers.
Also, no offense, but it appears the biggest grumblers would be a small mom and pop store who are probably selling this same product for twice the amount of money as a "big box" store, who are in fact lining their own pockets with profits made with their business links in the signatures at the bottom of their posts.
We all know the economy sucks right now, and money is tighter than ever. I have no loyalty to HD, and as a matter of fact, most of my purchases come from his direct competition, being Lowe's. It pays to shop around for the best prices possible.
I apologize to all for expressing my opinion, but believe it needed to be said!
