McMaster Carr keep all the profitable commercial customers who need guaranteed delivery. and Amazon clears out all the low profit/high cost - need an occasional bit of something for a project - type customers. Selling books/video online rather than in a store was a breakthrough area when Amazon got into it, ordering parts and materials isn't a new idea - Amazon is a lot less disruptive in this area. My guess is that the biggest hit will be small specialist model/hobby shops, but unless you are in a few big cities there aren't any of these anyway.
