McMaster's marketing is done well before you type the address into the browser. Their target custom is someone who needs to quickly get the item so they can go back to their job; make and price are not their concern -- to the extent that you can just email them and say "give me five more shelves" and their customer support people will look through your purchase history to match the model and paint scheme you bought. Or if you're a power plant, you can tell them to get the part to you RIGHT NOW, and they'll pay a courier to drive it from hundreds of miles away. (These are both true stories.) McMaster's customer behavior is the dream of almost every industry out there.
